Table 1 Summary of data from a two-arm comparative clinical trial

From: A simulation study for comparing testing statistics in response-adaptive randomization

  Response Failure Margins
Treatment 1 r 1 f 1 n 1
Treatment 2 r 2 f 2 n-n 1 = n 2
Margins r 1 + r 2 = r n-r = f 1 + f 2 = f n
  1. n: total number of patients; n 1, n 2: patients on treatment 1 and 2; r: total number of treatment successes; r 1, r 2: number of successes on treatment 1 and 2.
