Figure 1 Relative odds (logarithmic scale) on common cold (upper panel) and LRTI (lower panel) by the mean of the average daily temperature of the three days preceding the onset of an infection. The shaded area represents the 95% confidence interval of the relative odds curve. Based on a generalized additive model with binomial error and identity link.
