Change in clinical phenotype between baseline and four-years.

The clinical assessment included a change in trichiasis, entropion, conjunctivalisation, visual acuity and corneal opacification. The following comparisons were made: Surgery Arm to Epilation Arm (A v B), Surgery Arm to Epilation-Only (A v C) and Epilation-Only to Epilation-to-Surgery (C v D).
P-values were calculated by X2.
a Four individuals in the surgery arm and two individuals in the epilation arm did not have visual acuity measured at both baseline and four years.
b Ten individuals did not have paired corneal photographs from both baseline and four years.
