Objective: To determine the abnormal findings in the distal phalanx tuft of the hands (DPTH) in plain radiographs associated with the presence of rheumatoid arthritis (RA) in adults subjects. Methods: A systematic review was performed following the PRISMA guidelines using databases, such as, Medline, Embase, Bireme, Scielo, and Google Scholar. The main changes in the DPTH included erosion, reso...

The informational odds ratio (IOR) measures the post-exposure odds divided by the pre-exposure odds (ie, information gained after knowing exposure status). A desirable property of an adjusted ratio estimate is collapsibility (ie, the combined crude ratio will not change after adjusting for a variable that is not a confounder). Adjusted traditional odds ratios (TORs) are not collapsible. In cont...

In this paper, we will use Cochran-Mantel-Haenszel (CMH) statistics to analyse four data sets which have appeared in the literature. It is well known that tests based on the CMH statistics are equivalent to certain standard rank tests but here we show how CMH statistics also apply in less standard situations. In particular, examples are given for randomized block designs both with and without m...

The Miettinen & Nurminen (1985) method is often used for constructing confidence intervals of the difference in binomial proportions from stratified 2x2 samples. However, the weighting strategy proposed in their paper requires an iterative procedure to implement, which is nested within another iterative procedure for finding the confidence limits. This paper examines the Cochran-Mantel-Haenszel...

In 2018 Bornmann and Haunschild (2018a) introduced a new indicator called the Mantel-Haenszel quotient (MHq) to measure alternative metrics (or altmetrics) of scientometric data. this article we review statistics, point out two errors in literature, introduce indicator. First, correct interpretation MHq mention that it is still meaningful Second, variance formula for MHq, which leads narrower c...

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...

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 ...

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...
