Cumulative Association of hospitalization for sepsis or septicemia with risk of ischemic and hemorrhagic stroke, based on case-crossover analysis (using dataset 1^**)

Dataset 1	Ischemic Stroke	Hemorrhagic Stoke
	OR (95% CI)	OR (95% CI)
Hospitalization for sepsis/septicemia within 15 d before stroke	28.4 (20.0 –40.1)	12.1 (7.54–19.4)
Hospitalization for sepsis/septicemia within 30 d before stroke	13.9 (10.9–17.5)	16.0 (11.8–21.8)
Hospitalization for sepsis/septicemia within 90 d before stroke	6.46 (5.56–7.50)	12.3 (9.34–15.2)
Hospitalization for sepsis/septicemia within 180 d before stroke	4.97 (4.40–5.61)	9.78 (8.34–11.5)
Hospitalization for sepsis/septicemia within 365 d before stroke	3.92 (3.58–4.29)	7.38 (6.54–8.34)

OR indicates odds ratio; CI, confidence interval.

^*All p-values were < 0.0001

^**Dataset 1: In the first dataset all hospital admissions in which both stroke and sepsis were present on arrival were deleted.
