|---|---|---|---|---|---|---|---|
| P0 (Starting point) | P1 (Rate of change) | P2(End point) | P0(Starting point) | P1(Rate of change) | P2(End point) | ||
| Mixed-exposure | 50 | -73.0 (5.2) | 0.010 (0.344) | -187.7 (3.7x103) | -86.1 (4.4) | 0.334 (0.113) | -113.0 (2.1) |
| 150 | -69.8 (4.8) | 0.013 (0.242) | -185.2 (1.9x103) | -87.9 (6.1) | 0.289 (0.082) | -139.0 (3.9) | |
| Pure-exposure | 50 | -85.8 (8.2) | 0.011 (0.508) | -200.2 (5.1x103) | -80.2 (34.8) | 0.816 (1.612) | -98.1 (2.9) |
| 150 | -78.6 (11.3) | 0.016 (0.421) | -207.0 (3.0x103) | -79.5 (48.6) | 0.890 (0.713) | -137.4 (3.3) | |
Standard errors are shown in parenthesis.
Note: the decay function is, f(x)=P2 + (P0 - P2 ) × exp (-P1 × x)
