Time trends (medians and IDR) in the R600 and SAR between 1989 and 2019 by gender, across three age groups: 7–9 years, 10–12 years, and 13–15 years. Points and solid lines are the estimated values and smoothed estimated values, respectively, adjusted by region (the results are shown fixing the region to its mode). In the plots for R600 showing the estimated medians, the estimates below (above) 1/2 imply that the results were better (worse) than in the period 1989–2019 when comparing children of the same gender and age; for SAR the opposite holds. See Supplementary Information for more results including the uncertainty in the point estimates.
