Pre- and Post-ETROP Groups are compared to determine whether there is any discrepancy between the number of days scheduled between examinations, and the actual number of days elapsed, in patients treated with laser who subsequently developed a RD. Data was analyzed to assess provider reliability, to determine whether an outlier exists, and if so, could it be a confounding variable in the difference in outcomes between Pre- and Post-ETROP Groups. No such outlier was found. (E1 = examination # 1, E2 = examination # 2, etc). | ||||||||
