Notes: The effect sizes presented here are the random effects standardized mean difference (SMD). For those studies that reported the total number of school days missed for asthma per group, we divided the total number of school days missed by the number of subjects in each group to approximate the mean number of days missed per student. For the 13 studies that did not report a measure of variance, we extrapolated a variance from the studies reporting both mean days absent and a variance about this mean weighted by the sample size. We divided the mean number of school days missed by the duration of the study to calculate the mean number of school days missed per month.
