PR, prevalence ratio.

*For each outcome, the comparator for risk estimates was all subjects who did not have the outcome.

†Possible or probable.

‡Adjusted for age (in eight bands) and area.

§Adjusted for age and area, and also mutually adjusted.

¶81 of the 9844 subjects were excluded because somatising tendency score was missing.
