  1. aWilcoxon independent samples test statistic (and associated p values) for CMV status and all predictor variables except indoor/outdoor toilet age 11, which was analysed using the chi-square test and shows *the odds ratio for being CMV seropositive if indoor toilet age 11.
  2. bThe columns for CMV titre and IL-6 titre show the Spearman’s rho correlation with the predictor variables (and the associated p value).
