Table 3 Testing the need of univariate frailty in the model of time to recovery from obstetric fistula patients at Gondar university teaching and referral hospital (January, 2010–March, 2017)
Parameters for baseline distribution and frailty | Value | 95% CI |
|---|---|---|
P | 3.18 | 2.80 3.62 |
Theta | 0.53 | 0.32 0.87 |
LR test of theta = 0: chibar2 = 30.03 (Prob. > = ∣chibar2∣) < 0.001 | ||
