The role of thermography for diagnosing lumbar radiculopathy was evaluated by literature review and meta-analysis. From 81 relevant citations, 28 studies could be analyzed for diagnostic-accuracy data (sensitivity and specificity) and method. Diagnostic-accuracy data varied significantly between studies; therefore mean…

During the 1980's social cognitive theory has evolved as an explanation of human behavior. One of this theory's component constructs, self-efficacy, has received increasing attention as an antecedent to health related outcomes. The results of a meta-analysis examining studies which employed the construct of self-effica…

The objective of this study is to investigate the strength of the epidemiological evidence for a relationship between smoking and cervical cancer by analysis of recent literature. I conducted a meta-analysis of all eligible case-control studies published in English from 1977 to July 1990, with the primary intent of exa…

A review of research on the effects of met expectations for newcomers to organizations located 31 studies of 17,241 people. A meta-analysis found mean (corrected) correlations of .39 for job satisfaction and organizational commitment, .29 for intent to leave, .19 for job survival, and .11 for job performance. However,…

In primary studies, psychotherapy researchers frequently search for mediator and moderator variables that can help them understand the relationship between treatment and outcome. Yet a review of past psychotherapy meta-analyses revealed that none examined the possible role of mediator variables; and although all of the…

The physics, physiology, and pathology of electrical conductivity of milk are described. Based on a meta analysis, the use of electrical conductivity as a mastitis detection tool is discussed. Most reports were based on subclinical mastitis data. The gold standards of the different reports are discussed. With an overal…

Two recent meta-analyses have generated evidence for child and adolescent psychotherapy effects. However, critics note that such meta-analyses often include studies with methodological shortcomings which might invalidate their results. In the present study, we explored whether the results of the most extensive child/ad…

Systematic review and meta-analysis are possible as viable research techniques only through transparent reporting of primary research; thus, one might expect meta-analysts to demonstrate best practice in their reporting of results and have a high degree of transparency leading to reproducibility of their work. This ass…

OBJECTIVES: To empirically evaluate the performance of methods for estimating odds ratios and their corresponding standard errors from continuous end point data for meta-analysis. STUDY DESIGN AND SETTING: A database of randomized controlled trials of chronic depression treatments was used. Trials that reported both c…

The technique of meta-analysis was used to derive typical estimates of the risk of congenital malformations from oral contraceptive (OC) exposure in early pregnancy. Several definitions were used for non-exposure to reduce bias from this source. Congenital heart defects and limb reduction defects were analyzed separate…

The cesarean birth rate has continued to climb despite efforts to counteract it. A major reason for this rise is the practice of elective repeat cesarean. We conducted a meta-analysis that included 31 studies with a total of 11,417 trials of labor to evaluate the association between birth route after a cesarean and mor…

Although CBT has been found to be effective in the treatment of eating disorders, it is not clear if there are differences between treatment formats. We conducted a network meta-analysis (NMA) of randomized trials of broadly defined CBT comparing individual, group, guided self-help (GSH) and unguided self-help (USH) wi…

The relation of marital discord to the behavior problems of children was examined through a meta-analysis of the results of prior research. The sample comprised all published studies through 1988 that met criteria for the meta-analysis and that could be located through a combined computer and hand search of the literat…

A meta-analysis was carried out of the data from two double-blind, multi-centre studies with identical methodology which compared the effectiveness of treatment of elderly patients with zuclopenthixol and with other antipsychotic drugs. In one study, patients were treated for 4 weeks with either zuclopenthixol or melpe…

Abstract The aim of this meta-analysis was to compare the efficacy and safety profile of manidipine 20 mg with that of amlodipine 10 mg. A systematic research of quantitative data produced or published between 1995 and 2009 was performed. Head-to-head randomized controlled trials (RCTs) of 12 months minimum duration re…

The results are described of a meta-analysis of seven randomized trials that compared the clinical effects of the standard solution of WHO oral rehydration salts (ORS), containing 20 milligrams of glucose, and experimental ORS solutions, containing glycine, on 643 children with acute noncholera diarrhoea. The availabil…

BACKGROUND: Community-based rehabilitation is critical for functional recovery in older adults after hip fracture, yet the optimal strategy remains uncertain. Previous reviews are limited by the pooling of heterogeneous interventions and an incomplete assessment of evidence quality. This network meta-analysis (NMA) aim…

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…
