What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BackgroundHypoperfusion intensity ratio (HIR) and cerebral blood volume index (CBVI) have been shown to predict clinical outcome, but further validation is needed in patients initially presenting to non-thrombectomy centers.MethodsWe conducted a retrospective study of patients with an anterior circulation large vessel occlusion (ACLVO) who underwent computed tomography perfusion (CTP) scanning at a non-thrombectomy center and were transferred for consideration of thrombectomy. We evaluated the association of three measures of collateral status (HIR, CBVI, and a collateral score combining both measures) to 90-day modified Rankin scale (mRS).ResultsWe identified 497 eligible patients, of whom 93% underwent thrombectomy. After adjusting for covariates, ascending numerical CBVI was associated with 90-day mRS ≤ 2 in both overall patients and the recanalized subgroup (
