Urinary tract infections caused by extended-spectrum betalactamase-producing bacteria in children: a matched casecontrol study.
Extended-spectrum beta-lactamase (ESBL)-producing pathogens are emerging as a cause of urinary tract infections (UTI) worldwide. In this matched-case control study, clinical characteristics and associated risk factors for ESBL UTI were evaluated. In a total of 463 positive urine cultures, 48 (10.4%) (from 39 patients, 23 boys) were phenotypically ESBL-producing bacteria. The most frequently iso...

متن کاملBayesian Inference for Matched Case-Control Studies
Case-control studies occupy a central place in epidemiological research. The basic idea here is the comparison of a group (the “cases”) having the outcome of interest (normally some disease) with respect to a control group (those without disease) regarding one or more characteristics (exposure to certain external events). One of the early examples, which sparked a lot of debate in the fifties b...
متن کاملPower calculations for matched case-control studies.
Power calculations are derived for matched case-control studies in terms of the probability po of exposure among the control patients, the correlation coefficient phi for exposure between matched case and control patients, and the odds ratio psi for exposure in case and control patients. For given Type I and Type II error probabilities alpha and beta, the odds ratio that can be detected with a ...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
