*
Entropion treated as a linear variable (LR test for linearity: p = 0.07).
Entropion dropped from multivariable model as strongly linked to baseline lash type.
†
Compared to surgeon 4 who had the lowest recurrence rate. Likelihood ratio used to calculate p value for association between surgeon and recurrent TT.
‡
Compared to group with all trichiatic lashes epilated. Likelihood ratio used to calculate p value for association between lash type and recurrent TT.
