For quantitative variables, the median and quartiles 1 and 3 were reported; n (%) was reported for qualitative variables. MD/OR 95% CI, difference between medians (amniotic membrane minus conjunctival autograft) for quantitative variables or odds ratio for qualitative variables, with 95% confidence intervals. The odds ratio of an event is reported in the rows of the table.
