Table 2.
Estimated cross-shift ratios of 8-isoprostane levels in EBC collected from the wildland firefighters (n=12) working at prescribed burn shifts (burn days) compared to regular work shifts (non-burn days) using linear mixed effect model.
| Ratio | Post / Prea | MA / Preb | MA / Postc | |||
|---|---|---|---|---|---|---|
| Mean (95% CI)d | p-value | Mean (95% CI)d | p-value | Mean (95% CI)d | p-value | |
| 8-isoprostane | 1.08 (0.86 - 1.35) | 0.50 | 1.09 (0.78 - 1.50) | 0.61 | 1.01 (0.78 - 1.31) | 0.94 |
a
Ratios of post- to pre-shifts on burn days compared to ratios of post- to pre-shifts on non-burn days.
b
Ratios of next morning to pre-shifts on burn days compared to ratios of next morning to pre-shifts non-burn days.
c
Ratios of next morning to post-shifts on burn days compared to ratios of next morning to post-shifts non-burn days.
d
95% CI: 95% confidence interval.
