Steps need to be taken in order to ensure that this does not compromise the integrity of clinical trials; hence "Selection Bias and Covariate Imbalances in Randomized Clinical Trials" offers a comprehensive treatment of the subject and the methodology involved. This book:Provides an overview of the hierarchy of study designs, and justifies the position of randomised trials at the top of this hierarchy.Discusses the strengths and defects of randomisation, and provides real evidence to justify con 410 0$aStatistics in practice. 606 $aClinical trials$xStatistical methods$xEvaluation 606 $aRanking and selection (Statistics)$xEvaluation 606 $aSampling (Statistics)$xEvaluation 615 0$aClinical trials$xStatistical methods$xEvaluation. 615 0$aRanking and selection (Statistics)$xEvaluation. 615 0$aSampling (Statistics)$xEvaluation. 676 $a610/.72/4 700 $aBerger$b Vance$01842490 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911019538703321 996 $aSelection bias and covariate imbalances in randomzied clinical trials$94422644 997 $aUNINA
