BACKGROUND/AIM: Obesity is associated with increased incidence of gastroesophageal reflux disease (GERD), and it has been suggested that GERD symptoms may be improved by weight reduction. However, various patterns of bariatric surgery may affect symptoms of GERD due to the changed anatomy of stomach and esophagus. The…

BACKGROUND: The evaluation of the credibility of results from a meta-analysis has become an important part of the evidence synthesis process. We present a methodological framework to evaluate confidence in the results from network meta-analyses, Confidence in Network Meta-Analysis (CINeMA), when multiple interventions…

INTRODUCTION: The purpose of this study is to investigate the effect of peer support on patient anxiety during the perioperative period of coronary angiography or percutaneous coronary intervention (PCI). METHODS AND ANALYSIS: We will search the following databases (PubMed, Web of Science, EMBASE, Cochrane Library, CI…

BACKGROUND: Chuankezhi injection (CKZ) is gaining increasing popularity for chronic obstructive pulmonary disease (COPD) treatment, yet their comparative effectiveness and safety remain unclear. Therefore, we will provide a protocol to assess the efficacy and safety of CKZ for COPD. METHODS: From now until June 2020,…

INTRODUCTION: In recent years, a hypothesis has been raised that people with tuberculosis are at risk for developing venous thromboembolism (VTE). However, much remains to be understood about the interplay between VTE and tuberculosis. Therefore, through a global systematic review and meta-analysis, the current study a…

BACKGROUND: Gastric cancer is actually known as the sixth most frequent cancer and the second cancer-related cause of death worldwide. If studies giving an overview of current epidemiology of gastric cancer in Europe, Asia, and the USA are available, in Africa, studies reporting recent data on gastric cancer are sparse…

OBJECTIVE: The objective of this study is to investigate the potential dose-response association between alcohol consumption and the risk of mild cognitive impairment (MCI). METHODS: We will perform a dose-response meta-analysis (DRMA) of cohort studies to explore the dose-response relationship between alcohol intake…

BACKGROUND: Tuberculosis (TB) is a highly contagious and chronic disease. The microbiological examination to confirm children TB disease are limited due to paucibacillary Mycobacterium, specimens and detecting facilities. Considering these limitations in diagnosing children TB, new and reliable methods that detect chil…

INTRODUCTION: Cost-effectiveness analyses that use quality-adjusted life-years (QALYs) allow comparing the value for money of interventions across different health problems. Health state utility values (HSUVs) are crucial to calculate QALYs. These are weights attached to a given health state reflecting preferences in h…

BACKGROUND: Lumbar spinal stenosis (LSS) is a common and frequently-occurring disease in clinical practice. There are many interventions to treat it, and percutaneous endoscopic decompression (PED) is one of them, but their relative efficacy and safety remains unclear. Hence, the present study aims to synthesize the av…

BACKGROUND: Esophageal cancer (EC) is one of the most common malignant tumors with a poor prognosis and identified as one of the leading causes of cancer death in the world. Many studies have reported that the incidence of EC is closely related to the intake of alcohol, hot food, and hot beverages, as well as smoking a…

BACKGROUND: Diabetic mellitus erectile dysfunction (DMED) refers to erectile dysfunction (ED) secondary to diabetes. As people's lifestyle changes and the population ages, the incidence of DMED continues to increase. Many clinical trials have proven that Chinese medicine has a significant effect in the treatment of DME…

INTRODUCTION: Acute renal colic is one of the most common urological emergencies. While previous randomized controlled trials (RCTs) and pairwise meta-analyses only looked at the efficacy of 1 or 2 analgesics. It is not fully understood that the comprehensive ranking of the effectiveness and safeness of analgesics from…

INTRODUCTION: Drug users are more vulnerable to AIDS than the general population. While several interventions are effective for addressing HIV in injection drug users, no meta-analysis has yet been performed to compare interventions and determine the relative benefits of each. We intend to conduct a Bayesian network me…

BACKGROUND: Diabetic retinopathy (DR) is the leading cause of vision loss in adults of working age. Although existing systematic reviews of the prevalence of DR for mainland China have been reported, but several studies have been newly reported. Further some potential factors for DR are still discrepant and inconclusiv…

BACKGROUND: There is widespread obesity paradox in cardiovascular diseases, the cardiovascular influence from weight management remains controversial. Moreover, previous publications indicating that different weight reduction extent might lead to various results. Thus, it is of importance to reassess the cardiovascular…

INTRODUCTION: Prediction of pain using machine learning algorithms is an emerging field in both computer science and clinical medicine. Several machine algorithms were developed and validated in recent years. However, the majority of studies in this topic was published on bioinformatics or computer science journals ins…

BACKGROUND AND OBJECTIVES: Meta-analyses sometimes summarize results in the presence of substantial unexplained between-study heterogeneity. As GRADE criteria highlight, unexplained heterogeneity reduces certainty in the evidence, resulting in limited confidence in average effect estimates. The aim of this paper is to…

BACKGROUND: Mild cognitive impairment (MCI) is the clinical prognosis that leads to dementia. Early intervention of MCI is critical to protect against dementia. Exercise intervention has gained popularity for the management of MCI. Most current studies have focused only on improvements made by exercise interventions on…

INTRODUCTION: Demographic, behavioural and environmental factors have been associated with increased risk of head and neck cancer (HNC). We will review published reports and explore connections between risk factors and HNC incidence. This protocol aims to provide strategies for a systematic review and meta-analysis of…
