At present there is no widely accepted therapy for ankylosing spondylitis (AS), a progressive debilitating disease. The effectiveness of sulfasalazine in AS still lacks strong evidence, as well, the magnitude of its benefit is unknown. A meta-analysis was carried out to assess the effectiveness of sulfasalazine in AS.…

We identified 24 modern studies of childhood exposures to lead in relation to IQ. From this population, 12 that employed multiple regression analysis with IQ as the dependent variable and lead as the main effect and that controlled for nonlead covariates were selected for a quantitative, integrated review or meta-analy…

Cash and Deagle (1997) examined the associations between body image disturbance (BID) and the eating disorders (EDs) of anorexia nervosa (AN) and bulimia nervosa (BN) in a meta-analytic review. They found almost twice as many studies employing perceptual measures of body size evaluation compared to cognitive-evaluative…

Relevant to forensic practice, the Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993) established the boundaries for the admissibility of scientific evidence that take into account its trustworthiness as assessed via evidentiary reliability. In conducting forensic evaluations, psychologists and other…

The main aim of the treatment of hypertension is to reduce the incidence and severity of its complications. Despite some bias affecting the major clinical trials of diuretics and/or beta blockers, the results of the meta-analysis taking them into account demonstrate the effectiveness of the prevention of cerebrovascula…

The identification of effective treatments for uremic pruritus used a literature search of MEDLINE (1966 to March 1991), Index Medicus (1978 to March 1991), bibliographic reviews of textbooks, and pertinent articles. Only randomized controlled clinical trials were selected for analysis. Assessment of study quality was…

The data bases of 18 empirical studies were combined into one comprehensive data set and subjected to meta-analysis. The following trends were observed: (1) surgery has a significantly decompensating impact on the mental status of older persons, and the average effect size observed is modest (r = .37); (2) for all ment…

In this article we demonstrate that the difference in sleep between depressives and healthy controls varies systematically as a function of the mean age of the sample studied. The data were taken from 27 studies that had compared the sleep of drug-free depressed patients and age-matched healthy controls. In all, the st…

BACKGROUND: Atopic Dermatitis (AD) in children is a common chronic skin condition characterized by dry, itchy and inflamed skin. Various treatments have been applied in the management of AD in children, but the differences in efficacy of different treatment options have not been systematically summarized. The aim of th…

OBJECTIVE: To identify the most effective interventions to delay the progression of sarcopenia and potentially improve muscle strength and mass, with the ultimate goal of reversing sarcopenia, by comparing all pharmacological and non-pharmacological interventions. DESIGN: Systematic review and network meta-analysis.…

BACKGROUND: Inflammation has been implicated in psychosis, but its role in individuals at clinical (CHR) and genetic (GHR) high-risk remains unclear. We therefore conducted a network meta-analysis (NMA) to compare circulating cytokine levels across CHR, GHR, and healthy control (HC) groups. METHODS: We systematically…

BACKGROUND: Effective pain management following hip arthroplasty is critical for patient recovery. As a key component of multimodal analgesia strategies, nerve blocks are widely utilized for postoperative analgesia. However, the comparative efficacy of different nerve block techniques remains unclear. This study employ…

BACKGROUND: This study aimed to synthesize evidence on the relative effectiveness of antimalarial drugs used as chemoprevention of malaria in pregnancy (MIP) using network meta-analysis (NMA). METHODS: Searches for eligible studies were made in multiple electronic databases, including PubMed. Randomized controlled tri…

BACKGROUND: Diminished estrogen levels in women after menopause contribute to an elevated risk of decreased bone mineral density (BMD) and disturbed bone metabolism. Dietary supplements are extensively employed as substitutes for prescription drugs, serving as a significant approach to modulate bone metabolism and impr…

BACKGROUND: The shortage of donor hearts significantly limits heart transplantation. Innovative machine perfusion strategies have emerged to address the shortcomings of traditional static cold storage after brain death (SCS-DBD), potentially enhancing outcomes and broadening donor eligibility. We performed a systematic…

BACKGROUND CONTEXT: Nonspecific neck pain causes chronic pain, functional impairment, and adversely affects quality of life. It remains unclear whether exercise or other nonphysical therapies are more effective in improving nonspecific neck pain (NSNP), and the optimal dosage of exercise for alleviating NSNP has yet to…

OBJECTIVES: Temporal trends in comparative meta-analyses of interventions are well-recognized in the medical literature. For studies of diagnostic test accuracy (DTA), evidence of temporal trends is growing and the importance of assessing and reporting them has been highlighted in recent guidelines on postmarket survei…

OBJECTIVE: This study aimed to evaluate the effectiveness of robot-assisted gait training (RAGT) in treating lower extremity function in patients with cerebral palsy (CP) and compare the efficacy differences between different robotic systems. METHODS: PubMed, Web of Science, Cochrane Library, Embase, CNKI, VIP, CBM, a…

BACKGROUND: Multivariate meta-analysis (MVMA) jointly synthesizes effects for multiple correlated outcomes. The MVMA model is potentially more difficult and time-consuming to apply than univariate models, so if its use makes little difference to parameter estimates, it could be argued that it is redundant. METHODS: We…

In order to assess the strength of the 'evidence base' for the practice of otolaryngology a review of recent journal articles was undertaken. A review of all articles published during the period 1990-1994 in five major general otolaryngology journals was performed. The articles were classified according to a standardiz…
