The model was adjusted for age, sex, weight, height, smoking status, alcohol consumption, HP infection, diabetes history, hyperuricemia, cardiovascular diseases, MPV, bleeding in skin, bleeding in mucosa, bleeding in organ, treatment protocol (high-dose dexamethasone, oral prednisone, IVIG), MPD. In each case, the model was not adjusted for the stratification variable. Following variables excluded because of <20 obs. in a category: Diabetes history and bleeding in organ. OR – odds ratio; CI – confidence interval; HP – Helicobacter pylori; MPV – mean platelet volume; IVIG – intravenous immunoglobulin; MPD – mean platelet distribution.
