Sample sizes under 10 are indicated by a –. Insignificant coefficients between ±0.005 are indicated by 0. *** indicates regression coefficients significant at the 1% level; ** is for 5% and * at the 10%. Illness variables excluded due to small sample size. N for each meta-regression is shown in online supplemental appendix 4.
