To evaluate the relation between use of oral contraceptives and the incidence of breast cancer, the authors reviewed the epidemiologic literature and used quantitative methods to summarize the data. Study results for any use of oral contraceptives were pooled using a model that accounted for both interstudy and intrast…

BACKGROUND: Pulmonary rehabilitation (PR) is an effective intervention for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) following hospitalization. However, the optimal timing for initiating PR after admission remains controversial. This study conducted a systematic review and netwo…

OBJECTIVE: To estimate the comparative effectiveness of medical interventions in adults versus children. STUDY DESIGN: We identified from the Cochrane Database of Systematic Reviews (Issue 1, 2007) meta-analyses with data on at least 1 adult and 1 pediatric randomized trial with binary primary efficacy outcome. For ea…

Esophageal varices are a life threatening cause of gastrointestinal bleeding. Management includes both primary prevention of variceal bleeding and treatment of actively bleeding varices. Evidence from randomized controlled trials indicates that beta blockers and nitrates may prevent the initial episode of bleeding vari…

In comparative studies, lomefloxacin, a new difluorinated quinolone, exhibits broad antibacterial activity in vitro, similar or superior to that of other quinolones (enoxacin, ofloxacin, pipemidic acid, nalidixic acid, and norfloxacin) but less than that of ciprofloxacin. Lomefloxacin inhibited Neisseria gonorrhoeae, M…

The findings of some 26 papers covering the results of Andresen and Fränkel appliances, as analysed from cephalometric radiographs, are reviewed. These findings show a high degree of consistency. They have been combined to produce larger samples, and compared with a control group produced from reports of untreated…

The aim of comparative research in social epidemiology is to determine how risk factors for disease may vary within and between sociocultural and ethnic groups and in relation to outcomes. This aim assumes that measurement equivalence within and between social groups can be established, an assumption usually left untes…

Host defense, as it generally applies to humans, refers to the individual's ability to withstand infections. Human host defense mechanisms are numerous, diversified, complex, and often interdependent. The administration of drugs may influence some phases of immunocompetence mechanisms. The effect of several antimicrobi…

OBJECTIVE: We aimed to explore whether the prevalence of manic switch was underestimated in randomized controlled trials (RCTs) compared to observational studies (OSs). METHOD: Meta-analyses and simple and systematic reviews were identified by two reviewers in a blinded, standardized manner. All relevant references we…

OBJECTIVE: Currently, effective drugs for metabolic dysfunction-associated steatotic liver disease (MASLD) are limited, with treatment primarily focusing on diet and exercise. Recent studies suggest that gut microbiota-regulating drugs may offer therapeutic benefits. Therefore, our aim is to evaluate the efficacy of th…

Auditory hallucinations (AH) frequently persist in schizophrenia spectrum disorder despite antipsychotic treatment. Cognitive behavioral therapy (CBT) remains an established psychological intervention, whereas AVATAR (Audio Visual Assisted Therapy Aid for Refractory auditory hallucinations) therapy has recently been in…

OBJECTIVE: Glucose-free dialysate may heighten the risk of hypoglycemia, which is associated with seizures, stroke, and increased mortality. Incorporating an appropriate amount of glucose into the dialysate potentially helps to reduce the incidence of hypoglycemia. However, the efficacy and safety of glucose-containing…

BACKGROUND: Dysphagia compromises swallowing safety and efficiency, leading to malnutrition, dehydration, aspiration pneumonia, and frequent hospitalizations. Cortical neurostimulation therapies including transcranial direct current stimulation (tDCS), repetitive transcranial magnetic stimulation (rTMS), and theta burs…

OBJECTIVE: Although numerous endovascular technologies are available for lower extremity arterial disease (LEAD), a lack of direct, comparative evidence complicates optimal device selection. We conducted a network meta-analysis of randomized controlled trials (RCTs) to establish an evidence-based framework for device s…

BACKGROUND: Non-small cell lung cancer (NSCLC) patients harboring epidermal growth factor receptor (EGFR)-mutated who progressed on EGFR tyrosine-kinase inhibitor (EGFR-TKI) therapy have limited therapeutic options. There is still no consensus on the role of immune checkpoint inhibitors (ICIs) in NSCLC with EGFR mutati…

BACKGROUND: Hypertriglyceridemia is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD). We aimed to evaluate the efficacy and safety of apolipoprotein C-III (ApoC-III) inhibitors in patients with hypertriglyceridemia. METHODS: Electronic databases were systematically searched for randomised…

BACKGROUND: Optimal perioperative analgesia for upper gastrointestinal (UGI) surgery remains uncertain despite multiple available options. This network meta-analysis (NMA) evaluated the comparative effectiveness of local and regional analgesic techniques on postoperative pain and opiate consumption following open UGI s…

INTRODUCTION: Hand-foot syndrome (HFS) is a dermatological side effect of chemotherapies such as capecitabine and pegylated liposomal doxorubicin. Over recent years, numerous randomised controlled trials (RCTs) have investigated various pharmacological strategies to prevent HFS. Although urea cream and celecoxib have s…

STATEMENT OF PROBLEM: Extensive research has been carried out on the various aspects of diagnosing and treating peri-implantitis. However, clinical guidelines for the management of peri-implantitis based on high quality evidence are lacking. PURPOSE: The purpose of this systematic review with network meta-analysis was…

BACKGROUND: An increased number of women are expected to conceive after the diagnosis of early breast cancer. Most physicians recommend that pregnancy be delayed by 2 to 3 years after diagnosis of early breast cancer, but this recommendation is based on data from trials with small patient cohorts. Furthermore, a health…
