Table 5 Comparison of treatment versus placebo groups for the cumulative incidence of postoperative trachomatous trichiasis (TT) at 6 and 12 months with the severity of TT at baseline by multiple logistic regression controlling for age, sex, and bilateral lid surgery.
| TT severity at baseline | 6 month TT cumulative incident recurrence* | 12 month TT cumulative incident recurrence* | ||||
|---|---|---|---|---|---|---|
| Treatment group (%) | Placebo group (%) | p Value† | Treatment group (%) | Placebo group (%) | p Value† | |
| Epilated‡ (no eyelashes) | 4/15 (26.7) | 5/14 (35.7) | NS (0.700) | 5/16 (31.3) | 5/14 (35.7) | NS (0.796) |
| Minor TT (⩽5 eyelashes) | 7/22 (31.8) | 3/30 (10.0) | NS (0.075) | 7/22 (36.4) | 3/30 (10.0) | NS (0.075) |
| Major TT (>5 eyelashes) | 3/16 (18.8) | 8/14 (57.1) | NS (0.057) | 4/19 (21.1) | 8/13 (61.5) | 0.030 |
| Total | 14/53 (26.4) | 16/58 (27.6) | NS (0.911) | 17/57 (29.8) | 16/57 (28.1) | NS (0.955) |
*Denominator reflects number of eyelids; surgical failures were excluded from this table; surgical failure was defined as ⩾5 lashes at the lateral margins of the surgical incision (instead of centrally located) and touching the globe of the eye at the 3 month follow up; TT recurrence was defined as ⩾1 lash touching the globe of the eye following TT surgery.
†Multiple logistic regression; statistical significance (p⩽0.05).
‡Epilated cases defined as eyelids that had entropion but no lashes touching the globe, not included in the minor or major categories.
