Fig. 2: Estimates from INSPIRE.
From: Predicting age of respiratory syncytial virus infection from birth timing

A The penalized maximum likelihood estimate for the weight function (solid line) and corresponding 95% confidence intervals (dashed lines; n = 1713). B Penalized maximum likelihood estimates for the effect of non-birthdate covariates and corresponding 95% confidence intervals (n = 1713). Estimates were exponentiated to get hazard ratios. P-values test the null hypothesis that the hazard ratio is 1 against the alternative that it is not equal to 1. They are not adjusted for multiple testing. C Heatmaps giving the estimated probability of first infection age in days as a function of birthdate for infants born in the geographical region covering INSPIRE participants from 2012-2013. Probabilities were estimated assuming no non-birthdate risk factors (left) and older siblings, but no other risk factors (right). D The percent of the variance of each outcome (columns) explained by each covariate (rows). E The average estimated probability density function for INSPIRE participants born in June through December. Probability densities were computed conditional on being infected before age one year.
