Results from multivariate models for NSAIDs as a whole and by class and individual compounds
are reported in Figs 2 and 3 respectively. A statistically significant increase in the CKD
risk was found for current users of oxicams (adj. OR: 1.74; 95% CI: 1.20–2.54; p = 0.004) and,
concerning single ingredients, for current users of meloxicam (adj. OR: 1.98; 95% CI: 1.01–
3.87; p = 0.046), piroxicam (adj. OR: 1.95; 95% CI: 1.19–3.21; p = 0.008) and ketorolac (adj.
OR: 2.54; 95% CI: 1.45–4.44; p = 0.001). No statistically significant associations were found for
larger time windows.
