DEFINITION:<br/>A designation used to segregate study subjects into collections in order to balance the study for analysis. The stratum group is made up of a combination of stratification criterion answers, which ultimately is used to assign study subjects or experimental units to arms on a study.<br/><br/>EXAMPLE(S):<br/>A given study may want to require even distribution of gender and age so stratum groups may be defined as:  males under 18, males 18 and over, females under 18, and females 18 and over.<br/><br/>OTHER NAME(S):<br/><br/>NOTE(S):<br/>

Notes: DEFINITION: <br/>An integer that identifies the stratum group to study personnel, such as the statistician and registrars. <br/><br/>EXAMPLE(S):  <br/>Patient age (years)<br/>Stratum A<br/>Gender<br/>Two-year survival probability<br/>Disease Type<br/>Treatment Cohort<br/><br/><br/>OTHER NAME(S):  <br/><br/>NOTE(S):<br/>This index is used to cross-reference the stratum group and set of arms during registration. It is provided to perform a lookup in the randomization book or statistical algorithm when performing randomization.<br/><br/>Text is captured using the originalText attribute of the INT.NONNEG data type.<br/>
