From: The cost of systemic corticosteroid-induced morbidity in severe asthma: a health economic analysis
Adjusted differences, between OCS exposure groups, in annual non-asthma prescription costs per patient across age-groups. Difference in annual non-asthma drug cost per patient at each age-group between those with high OCS exposure and those without OCS exposure (red) and between those with low OCS exposure and those without OCS exposure (blue). Differences in costs per patient are adjusted for confounders (sex, region and background morbidity) and calculated holding confounders at the sample mean. Outer lines represent 95% confidence intervals around these estimates
