Logistic regression: independence of THRIVE score from recanalization or device

	Odds ratio	95% CI	P value
Model 1: good outcome (all Solitaire)
THRIVE score	0·67	0·58–0·79	<0·001
Model 2: good outcome (all Solitaire)
THRIVE score	0·68	0·58–0·80	<0·001
Successful recanalization (TICI 2b/3)	3·1	1·54–6·10	0·001
Model 3: good outcome (SWIFT RCT)
THRIVE score	0·69	0·53–0·90	0·006
Model 4: good outcome (SWIFT RCT)
THRIVE score	0·63	0·50–0·79	0·007
Randomized to Solitaire	1·18	0·49–2·82	0·71

All models in the table are logistic regression models of good outcome (mRS 0–2) at 90 days.

In Model 1, THRIVE score predicts good outcome in all patients treated with the Solitaire device (SWIFT + STAR).

In Model 2, THRIVE score and successful recanalization predict good outcome in all patients treated with the Solitaire device (SWIFT + STAR). Addition of successful recanalization to the model does not alter the relationship of THRIVE score and outcome (Model 2 compared with Model 1).

In Model 3, THRIVE score predicts good outcome in all patients in the SWIFT RCT.

In Model 4, THRIVE score and device assignment (randomization to Solitaire) predict good outcome in all patients in the SWIFT RCT. Addition of device assignment to the model does not alter the relationship of THRIVE score and outcome (Model 4 compared with Model 3). Addition of device assignment to the model does not alter the relationship of THRIVE score and outcome (Model 4 compared with Model 3).
