Cumulative Association of hospitalization for sepsis or septicemia with risk of ischemic and hemorrhagic stroke, based on case-crossover analysis (using dataset 2^**)

Dataset 2	Ischemic Stroke	Hemorrhagic Stoke
	OR (95% CI)	OR (95% CI)
Hospitalization for sepsis/septicemia within 15 d before stroke	5.28 (3.65 – 7.64)	3.45 (2.04–5.84)
Hospitalization for sepsis/septicemia within 30 d before stroke	6.35 (5.07–7.94)	4.69 (3.32–6.62)
Hospitalization for sepsis/septicemia within 90 d before stroke	4.78 (4.17–5.49)	4.60 (3.68–5.76)
Hospitalization for sepsis/septicemia within 180 d before stroke	4.23 (3.85–4.67)	4.53 (3.86–5.32)
Hospitalization for sepsis/septicemia within 365 d before stroke	3.86 (3.59–4.15)	4.14 (3.68–4.67)

OR indicates odds ratio; CI, confidence interval.

^*All p-values were < 0.0001

^**The second dataset deleted all admissions in which any kind of stroke and sepsis occurred in the same admission from all three years of data. Thus the comparison was only between separate admissions for stroke and sepsis.
