Table 4.
Risk ratio estimates, for the three life course epidemiology models with the best model fit criteria, comparing the risk of MS in individuals reporting the lowest levels of summer sun exposure to those reporting highest levels of summer sun exposure
| Model | Risk ratio a (95% CI) |
|---|---|
| Accumulation model | 1.47b (1.24, 1.74) |
| Ordinal (0 to 3 age intervals) | |
| Critical period model | 1.29 (1.14, 1.45) |
| Age interval 0–5 years | |
| Critical period model | 1.29 (1.13, 1.47) |
| Age interval 11–15 years |
a
Estimates adjusted for age, sex and country.
b
Estimate is for a three-unit change in exposure (three age intervals with low summer sun exposure compared with three age intervals with high summer sun exposure).
