Table 4.
Significant lag-specific effects of prenatal exposure to NO2 or PM2.5 on children’s MDI and PDI, for a 1 SD-unit increase in NO2 or a 1 SD-unit increase in PM2.5, where SD is estimated using exposure levels within the entire pregnancy
| Outcome | Exposure | Lag | Estimate (Bonferroni-adjusted CI) |

| lag 30 | -0.190 (-0.345, -0.035) | ||
| 2.16-unit increase in PM2.5 | lag 17 | -0.052 (-0.104, -0.000) | |
| lag 18 | -0.052 (-0.104, -0.001) | ||
| MDI at age 3 | 5.81-unit increase in NO2 | lag 29 | -0.205 (-0.395, -0.016) |
| 2.16-unit increase in PM2.5 | lag 27 | -0.071 (-0.141, -0.002) | |
| lag 28 | -0.074 (-0.143, -0.005) | ||
| lag 29 | -0.075 (-0.146, -0.004) | ||
| PDI at age 3 | 2.16-unit increase in PM2.5 | lag 12 | 0.091 (0.000, 0.181) |
