(A) shows Kaplan Meier curves comparing survival of participants with mild stroke in the control and intervention groups.
(B) shows Kaplan Meier curves comparing survival of participants with moderate stroke in the control and intervention groups.
(C) shows Kaplan Meier curves comparing survival of participants with severe stroke in the control and intervention groups.
(D) shows Kaplan Meier curves comparing survival of participants with very severe stroke in the control and intervention groups. The p values were obtained from the log rank tests.
Mortality within 7 days was higher in the intervention group compared to controls (RR 13.1, 95% CI 3.3–52.9). There was no difference in 30-day mortality between the two groups (RR 1.2, 95% CI 0.5–2.6). There was better 30-day survival in patients with severe stroke in the intervention group compared to controls (P = 0.018). The median survival time was 30 days (IQR 29–30 days) in the control group and 30 days (IQR 7–30 days) in the intervention group. In the intervention group, 41patients (32.3%) died in hospital compared to 23 (18.1%) in controls (P < 0.001). The median length of hospital stay was 8 days (IQR 5–12 days) in the controls and 4 days (IQR 2–7 days) in the intervention group. There was no difference in functional outcomes between the groups (RR 0.9, 95% CI 0.4–2.2).
