Top,A: change in FEV1in patients who have not been treated with antibiotics during the index exacerbation in the procalcitonin-guided group (n = 61) and standard-therapy group (n = 30). p Values compare the change in FEV1over time between both groups.Bottom,B: change in FEV1in patients who have been treated with antibiotics during the index exacerbation in the procalcitonin-guided group (n = 41) and standard-therapy group (n = 76). p Values compare the change in FEV1over time between both groups.
