Meta-analysis combines results from multiple longitudinal studies to describe life course variation by age and sex for quantity of drinking per typical occasion (20 studies) and frequency of drinking during one month (27 studies). There is cross-study heterogeneity for the Time 1 means of the drinking variables blockin…

BACKGROUND AND OBJECTIVES: Chronic subdural hematoma (cSDH) is a common neurosurgical condition, particularly in elderly patients. Middle meningeal artery embolization (MMAE) has emerged as a promising intervention, while statins have been explored for their anti-inflammatory and angiogenesis-modulating properties. Thi…

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…

The effectiveness of memory training for the elderly was examined through a meta-analysis of pre-to-posttest gains on episodic memory tasks in healthy subjects aged 60 or above. Pre-to-posttest gains were found to be significantly larger in training groups (0.73 SD, k = 49) than in both control (0.38 SD, k = 10) and pl…

OBJECTIVE: Evaluate the treatment of Premenstrual Dysphoric Disorder (PMDD) with antidepressants and combined oral contraceptives (COCs) in order to identify the most appropriate treatments available, with the best tolerability and acceptability. RESULTS: Sixteen studies were included in the systematic review, of whic…

Meta-analysis (eight general population longitudinal studies) describes the relationships (regressions) between quantity per occasion and depressive symptomatology over time. Quantity and depression are the strongest and most consistent predictors of final levels of themselves in all data sets. Age significantly and co…

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,…

Coffee consumption has been linked to risk of colorectal cancer theoretically, but the findings were conflicting from observational studies. Results from the recent meta-analysis suggested a moderate favorable effect of coffee consumption on colorectal cancer risk, especially for colon cancer. However, the relationship…

Placebo controlled trials of methotrexate, auranofin, penicillamine, azathioprine, sulphasalazine, gold sodium thiomalate and chloroquines were subjected to meta-analysis. The difference between drugs and placebo in the erythrocyte sedimentation rate was 8.8 mm/hr [95% confidence interval (CI), 6.4-11.3]. In multiple l…

A literature search revealed 51 controlled clinical studies on the effectiveness of acupuncture in chronic pain. These studies were reviewed using a list of 18 predefined methodological criteria. A maximum of 100 points for study design could be earned in four main categories: (a) comparability of prognosis, (b) adequa…

To evaluate variability in the reported accuracy of fluoroscopically detected coronary calcific deposits for predicting angiographic coronary disease, we applied meta analysis to 13 consecutively published reports comparing the results of cardiac fluoroscopy with coronary angiography. Population characteristics and tec…

Graphics displaying all confidence intervals around a point estimate have been referred to as P-value functions and consonance intervals. We recommend use of the term confidence interval function (CI function) rather than P-value function. The CI function is useful because it simultaneously depicts point estimation, va…

BACKGROUND: Long bone fractures may exhibit nonunion/delayed union and the precise mechanism underlying this devastating condition remain unknown. More recently, a series of meta-analyses have examined the effect of local administration of platelet-rich plasma (PRP) in patients suffering from nonunion/delayed union fra…

Studies designed to examine effects of weight reduction by dieting on total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-C), high-density-lipoprotein cholesterol (HDL-C), very-low-density-lipoprotein cholesterol (VLDL-C), and triglycerides (TGs) have reported inconsistent results. The purpose of this stud…

It is a well-known fact that dietary fiber is recognized as one of the essential components of a healthy diet. The aim of this paper was to investigate the impact of dietary fiber on the incidence and mortality of various types of cancer, the current evidence in this field, and the biases of this evidence using the met…

The purpose of this meta-analysis was to estimate the effects of heparin flush and saline flush solutions on maintaining patency, preventing phlebitis, and increasing duration in peripheral heparin locks. The average effect size (d value) across 15 studies with a total sample size of 3,490 was .0573 for patency (clotti…

Developmental change in twin similarity was examined with age contrasts in a meta-analysis of twin studies from 1967 through 1985. Intraclass rs were coded from 103 papers that included data for monozygotic or dizygotic twins, or for both, on personality or intelligence variables. Analyses indicated that there was a ge…
