TABLE 1.

Sensitivity of Relative Heat and Cold Effects to Inclusion of Pollution Variables in the Temperature–Mortality Model

Pollutant Adjustment	Heat Effect			Cold Effect
	Estimate %	95% PI	No. Communities	Estimate %	95% PI	No. Communities
Without PM10	3.7	2.6–4.7	63	4.7	2.6–6.8	63
With PM10	3.2	2.1–4.4		4.5	2.4–6.7
Without O3	3.5	2.8–4.2	87	4.3	3.0–5.6	87
With O3	3.2	2.5–3.9		4.3	3.0–5.7

Results without pollution adjustment include only days and communities with pollution data available. Ozone is at lag 0 days; PM₁₀ is at lag 1 day.

PI indicates posterior interval.
