Figure 3

Time trends (medians and IDR) in the SU60, BAH, and SBJ 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 showing the estimated medians, the estimates above (below) 1/2 imply that the results were better (worse) than in the period 1989–2019 when comparing children of the same gender and age. See Supplementary Information for more results including the uncertainty in the point estimates.
