  1. TC-TC: thrombocytopenia on Day 1 and Day 4; NP-TC: normal platelet count on Day 1 but thrombocytopenia on Day 4; TC-NP: Thrombocytopenia on Day 1 with recovery to normal platelet count on Day 4; NP-NP: normal platelet count entire course; IQR: interquartile range; SAB: S. aureus bacteremia
  2. Data are no. (%) unless otherwise indicated; N = 752 due to missing platelet counts at day 4
  3. p-values were adjusted using Hommel’s multiple testing method
