AICs and estimated point estimates (Hazard ratio for PH models or time ratios for AFT models) for Herpes Zoster from various survival models.
| Model | Model type | AIC | Point estimate (95% CI) exponentiated |
|---|---|---|---|
| Cox | PH | 543,745.1 | 0.915 (0.887, 0.944) |
| Weibull | PH and AFT | 43,607.56 | 0.908 (0.880, 0.936) |
| Log‐logistic | AFT | 42,572.3 | 1.009 (1.006, 1.012) |
| Generalised gamma | AFT | 42,327.88 | 1.009 (1.006, 1.012) |
PH Proportional hazards; AFT accelerated failure time.

Note: models all excluded general practise; this made little difference to the Cox model estimates.
