This paper takes a deeper look into uncertainty assessment of the Mantel–Haenszel estimator (MHE). In homogeneity case, all developed confidence intervals for risk ratio and difference behave acceptably, even in therare events situation. For heterogeneity, non-parametric bootstrap approachprovides with acceptable coverage,depending on number studies. ratio, situation is morecomplex as typically...

For more than two decades, the Mantel-Haenszel (MH) procedure has been used to detect differential item functioning (DIF). A bibliometric study of this use of the MH procedure was conducted in order to better understand the current state of the research activity in the area (in terms of quantitative indicators and impact). Initially, we drew up a map of scientific output about this research are...

OBJECTIVE To compare the safety and efficacy of adjunctive aripiprazole versus placebo for antipsychotic-induced hyperprolactinemia. METHODS POPULATION adult patients presenting with antipsychotic-induced hyperprolactinemia diagnosed by prolactin level with or without prolactin-related symptoms. INTERVENTIONS adjunctive aripiprazole vs. adjunctive placebo. OUTCOME MEASURES adverse even...

INTRODUCTION Research into therapeutic hypothermia following traumatic brain injury has been characterised by small trials of poor methodological quality, producing variable results. The Cochrane review, published in 2009, now requires updating. The aim of this systematic review is to assess the effectiveness of the application of therapeutic hypothermia to reduce death and disability when admi...

BACKGROUND Controversy surrounds prostate-specific antigen (PSA) testing for prostate cancer screening, especially among elderly men aged 75 and older. This study examines whether patient age results in differential use of PSA testing and if organizational attributes such as communication, stress, decision making, and practice history of change predict PSA testing among men aged 75 and older. ...

BACKGROUND AND OBJECTIVES Urinary retention is a common condition in the post-anesthetic care unit (PACU). Vesical overdistension and consequent damage of the detrusor muscle of the urinary bladder represent situations that can be prevented. The ultrasound allows the reliable measurement of the urinary volume, determining the prevalence of postoperative vesical distension. The objective of the ...

INTRODUCTION Genetic susceptibility to complex diseases has been intensively studied during the last decade, yet only signals with small effect have been found leaving open the possibility that subgroups within complex traits show stronger association signals. In rheumatoid arthritis (RA), autoantibody production serves as a helpful discriminator in genetic studies and today anti-citrullinated ...

This study uses simulated data to compare two methods of calculating Differential Test Functioning (DTF): Raju’s DFIT, a parametric method that measures the squared difference between two Test Characteristic Curves (Raju, van der Linden & Fleer, 1995), and a variance estimator based on the Mantel-Haenszel/Liu-Agresti method, a non-parametric method enabled in the DIFAS (Penfield, 2005) program....

INTRODUCTION We performed a systematic review of the literature on preputial reconstruction (PR) during hypospadias repair to determine the cumulative risk of preputial skin complications and the influence of PR on urethroplasty complications, namely, fistula formation and overall reoperation rate of the repair. MATERIALS AND METHODS A systematic search of the literature published after 06/19...

Numerous studies have examined the empirical evidence concerning the influence of demographic and socio-economic factors influencing child immunization, but no documentation is available which shows the actual impact of antenatal care (ANC) visits on subsequent child immunization. Therefore, this paper aims to examine the net impact of ANC visits on subsequent utilization of child immunization ...
