Comparison of Pooled Estimates From Other Meta-Analyses of Ozone and Mortality^*

Meta-Analysis Study	Percent Increase (95% Interval)
Thurston and Ito20	0.89 (0.56 to 1.22)
Thurston and Ito20	1.37 (0.78 to 1.96)*
Stieb et al 23	1.12 (0.32 to 1.92)
Levy et al 21	0.98 (0.59 to 1.38)
Anderson et al24	1.11 (0.55 to 1.67)
Present meta-analysis†	0.87 (0.55 to 1.18)

^*Included only studies that considered a nonlinear relationship between temperature and mortality.

^†Percent increase (95% posterior interval) in mortality per 10-ppb increase in daily average ozone at short-term lags (single-day lags of 0, 1, or 2 days or a 2-day average of lags 0 and 1 or lags 1 and 2.
