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

	Ischemic		Hemorrhagic
	OR	95% CI	OR	95% CI
Hospitalization for sepsis/septicemia 0–15 days before stroke	5.28	3.65–7.63	3.45	2.04–5.84
Hospitalization for sepsis/septicemia 15–30 days before stroke	4.58	3.56–5.89	3.74	2.52 – 5.54
Hospitalization for sepsis/septicemia 30–90 days before stroke	3.34	2.85–3.91	3.63	2.77–4.76
Hospitalization for sepsis/septicemia 90–180 days before stroke	3.14	2.76–3.57	3.62	2.93–4.48
Hospitalization for sepsis/septicemia 180–365 days before stroke	2.94	2.65–3.26	3.25	2.73–3.86

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.
