OBJECTIVE: To describe associations between serum inhibin-b and sperm counts, adjusted for effect of time of blood sampling, in larger cohorts than have been previously reported. DESIGN: Cross-sectional studies of spermatogenesis markers. SETTING: Four European and four US centers. PATIENT(S): Fertile men (1,797) were included and examined from October 1996-February 2005. INTERVENTION(S): The study was observational and therefore without any intervention. MAIN OUTCOME MEASURE(S): Associations between inhibin-b and semen variables controlled for time of blood sampling and other covariates. RESULT(S): Inhibin-b decreased about 2.00% per hour from 8 am-12 pm and then about 3.25% per hour from 12 pm-4 pm. …

The purpose of this study was to evaluate inadequate hemodialysis risk in patients with body weights in the upper quartile of a sample distribution using the urea reduction ratio (URR). Using a case-control design and a simple (n = 315) of hemodialysis (HD) patients, postdialysis weights were divided into quartiles based with a cut-off value at the upper quartile, which was equal to >/= 81 kilograms (kg). The dichotomous outcome, URR >/= 65% and URR /= 81 kg group were given more dialysis session time in minutes and used higher efficiency dialyzers as indicated by the coefficient of ultrafiltration (KUf), …
