^‡Multivariable model only includes variables for which data are shown below because all others were lacking significance.

*Three participants with missing BMI could not be included in the log-binomial regression model because the outcome did not vary in this group.

^†One participant with unknown education level was excluded from analysis because the outcome did not vary in this stratum.
