B) with 95% confidence intervals (CI) from linear mixed models, with a random intercept for each child, and a repeated term for each child across each repeated observation, with autoregressive covariance structure. *: Temperature squared was excluded from this model as it was not statistically significant. Bolded text indicates significant at p<0.05.
