BACKGROUND Our Center recently conducted a systematic review of the manifestations and management of chronic insomnia in adults. The efficacy and safety of benzodiazepines and nonbenzodiazepines, relative to placebo, were compared indirectly. OBJECTIVES Determine how the results of indirect comparisons made in the review compare with the results of direct comparisons, as well as with estimate...

These supporting online materials have 9 sections. Section 1 describes the known population and summation methods of personal network size estimation and how we used the data from our study to decide between them. These personal network size estimates are used in the network scale-up and generalized network scale-up estimates described in Sections 2 and 3. Next, Sections 4 and 5 describe the mu...

In standard treatments of probability, Pr(A|B) is defined as the ratio of Pr(A intersectionB) to Pr(B), provided that Pr(B)>0. This account of conditional probability suggests a psychological question, namely, whether estimates of Pr(A|B) arise in the mind via implicit calculation of Pr(A intersectionB)/Pr(B). We tested this hypothesis (Experiment 1) by presenting brief visual scenes composed o...

BACKGROUND In network meta-analyses, several treatments can be compared by connecting evidence from clinical trials that have investigated two or more treatments. The resulting trial network allows estimating the relative effects of all pairs of treatments taking indirect evidence into account. For a valid analysis of the network, consistent information from different pathways is assumed. Consi...

یکی از علت های شکست و عدم موفقیت در تکنیک های کمک باروری(art) قطعه قطعه شدن dna اسپرم انسانی است، که ممکن است با انکوباسیون طولانی مدت اسپرم در دمای 37 درجه سانتی گراد به وجود آید. لذا در این مطالعه میزان قطعه قطعه شدن و آپوپتوز dna اسپرم انسانی بعد از آماده سازی به روش direct swim-up در زمان های مختلف انکوباسیون به وسیله تست scd و تکنیک tunel مورد ارزیابی قرار گرفت. در این مطالعه آینده نگر، ب...

(co) variance components and genetic parameters for growth traits in arman sheep were estimated, using data collected during an 11-year period (1999-2010), by applying the restricted maximum likelihood (reml) procedure under univariate and bivariate animal models. the studied traits were body weight of lamb at birth (bw), body weight at 3 months of age as weaning weight (ww), body weight at 6 m...

Variances and covariances for birth weight, gain from birth to weaning (ADG), and 205-d weight were obtained from a sire-dam model and a sire-maternal grandsire model for a herd of Angus and a herd of Hereford cattle. Estimates of direct additive genetic variance (sigma 2A), maternal additive genetic variance (sigma 2M), covariance between direct and maternal additive genetic effects (sigma AM)...

Weaning weights from nine parental breeds and three composites were analyzed to estimate variance due to grandmaternal genetic effects and to compare estimates for variance due to maternal genetic effects from two different models. Number of observations ranged from 794 to 3,465 per population. Number of animals in the pedigree file ranged from 1,244 to 4,326 per population. Two single-trait an...
