^aThe primary analyses, including only data from the participating centers.

^bSensitivity analyses 1, including data from Whittaker et al. (27) taking the whole of England as the reference value (resulting in overestimation of the relative risk).

^cSensitivity analyses 2, including data from Whittaker et al. (27) taking the borough of Lewisham (London) as the reference value (resulting in underestimation of the relative risk).

^dSensitivity analyses 3, including data from two large American case series (12, 13). n, number of included cases. RR, relative risk. 95% CI, 95% confidence interval.
