Hi Tom:

Enclosed please find the summary of IQRs applied in the estimates in Table 4 and 5. Yes,

different IQRs were developed and used for the different averaging time, for each of the

pollutants and the outcomes. Let me know if you have any questions.

Best wishes,

Wei

Hi Wei,  

Thank you very much for your quick response.  I was able to locate the IQRs for the 4‐hr MA.

In looking through the results, it appears as though the IQR for the 12‐hr avg was 48.4,  

This led me to believe that different IQRs were used for each of the different averaging

times for each of the different pollutants.  I'm specifically interested in the IQRs used for

the 1‐hr and 12‐hr results in Table 4 and the 30‐min, 2‐hr, 12‐hr and 24‐hr results in Table

5.  I would really appreciate any information you could provide regarding these results.

Thank you,

Tom

Tom:

During the study period, the IQRs for 4‐hr MA PM2.5, BC, NO2, SO2, CO, and O3 were:

51.84, 2.02, 13.7, 6.3, 0.66, 36.15 (10‐hour max values of hourly ozone was used in the

estimates)

Thank you for your interest in our work, and let us know if you have further inquiry!

Best wishes,

From: 2012 paper in AJE on autonomic and vascular dysfunction

Dr. Zhu,   

I have been reviewing your 2012 paper, "Air pollution and autonomic and vascular dysfunction

in patients with cardiovascular disease: interactions of systemic inflammation, overweight,

and gender" (AJE 176(2): 117‐126), for inclusion in our upcoming Integrated Science

Assessment on Oxides of Nitrogen.  I was able to find the IQR that you used for the 4‐h

effect estimates in Table 4, but was hoping that you could send me the IQR values used for

the other exposure periods in Tables 4 and 5?

Thank you,
