^{a} Infectious episodes before six months of age.

^{b} Bivariate conditional logistic regression using matched sets of cases with 1–2 referents.

^{c} Multivariate conditional logistic regression using matched sets of cases with 1–2
referents, with each exposure adjusted separately for infant feeding and socioeconomic
status (compare Table 1).

^{d} Corresponding P-value for the multivariate analyses.

^{e} Preliminary version of this result has previously been included in review articles/book
chapters [22-27].
