This commentary presents a new estiof matching variables, unmatched varimator of the variance of the natural log of ables, or both. This notation encompasses the Mantel-Haenszel odds ratio and illusthe full spectrum of matched and untrates its application in typical case-control matched designs. For example, in the pairdesigns. In contrast with any single previmatched study, MI and Mo are alway...

Writing the variance of the Mantel-Haenszel estimator under the null of homogeneity and inverting the corresponding test, we arrive at an improved confidence interval for the common risk difference in stratified 2 × 2 tables. This interval outperforms a variety of other intervals currently recommended in the literature and implemented in software. We also discuss a score-type confidence interva...

The current study research showed the nature and potential sources of gaps in mathematics achievement between English language learners (ELLs) non-English (non-ELLs). gap was examined using three DIF methodologies: including Mantel-Haenszel procedure, Rasch model, Hierarchical Generalized Linear Model (HGLM). These were conducted at item level contrast to total test level. Results revealed that...

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...

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...
