Page 161. Part II. Caption for Figure 5 should read:
City-specific relative risks in the ACS Study.
Page 162. Part II. Caption for Figure 6 should read:
Shape of concentration-response function (with standardized residuals plotted) for cities in the ACS Study.
Page 174. Part II. Table 32. After "O3 (ppb)" in the left column, append footnote b that reads:
"b Based on daily 1-hour maximum concentrations."
Page 178. Part II. Table 33. For O3 (second row from bottom), in the column "Description of Covariate and Source of Data", the entry should read exactly like the other three:
"Daily average concentrations averaged by year for 1980; from residential, commercial, or mobile monitors"
Page 259. Health Review Committee's Commentary. Gaseous Copollutants section. The third sentence should read:
"For four gaseous copollutants (carbon monoxide, nitrogen dioxide, ozone, and sulfur dioxide), city-specific annual means of daily average concentrations from the year 1980 were obtained from AIRS and used in the reanalysis (see Appendix E, Part II)."At the end of the same paragraph, add this sentence:
"For this analysis, the ozone values were based on daily 1-hour maximum concentrations."
Part II, Appendix E (available on request) Page 5. Gaseous Copollutants section. The second sentence should read:
"Daily average concentrations of NO2, sulfur dioxide, ozone, and carbon monoxide were obtained from 1980 to 1989, in addition to the daily one-hour maximum concentrations of ozone."
