Table 3.

Hazard ratio (HR) and 95% confidence intervals for the association of daily maximum daily temperature and all-cause hospital admissions (ACHA) based on Lag 2- Lag 1 discrete-time model structure. Due to the large number of categorical factors, treatment clinics associations were not reported. Bold indicates statistically significant hazard ratio at p < 0.05.
