was statistically insignificant when using longer lag periods. Significant effects of cold exposure were observed for all lag periods examined. For example, a 1 C decrease in temperature below the MMT corresponded to a 3.81% (95%CI: 1.48%, 6.14%) increase in OHCD mortality when using lags of 0e21 days. The effects of hot temperature were restricted within the first 3 lag days. A 1 C increase in temperature above the MMT lead to a 4.61% (95%CI: 0.88%, 8.34%) increase in OHCD mortality when using lags of 0e3 days. We did not observe any significant effects of temperature changes on IHCD mortality, regardless of lag length used.
