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
Background and PurposeThe first pass effect (FPE), achieving near-complete revascularization in a single pass, predicts good outcomes in mechanical thrombectomy (MT). FPE30, achieving FPE within 30 min of groin puncture, is a novel procedural metric proposed as an indicator of maximal procedural and systems-level efficiency. This study aimed to determine the incidence of FPE30 and explore potential predictors in a real-world clinical setting, thereby assessing its utility as a performance benchmark.MethodsWe retrospectively analyzed 274 consecutive MT patients at a comprehensive stroke center. The primary outcome was FPE30, defined as achieving mTICI 2c-3 in a single pass within 30 min of groin puncture. Patient characteristics were compared between FPE30 and FPE > 30 groups.ResultsOf 274 patients, 52 (19.0%) achieved FPE; 43 (82.7%) met the FPE30 benchmark. No statistically significant predictors of FPE30 were found. Trends indicated FPE30 was less common in internal carotid artery (ICA) terminus occlusions (7.0% vs. 33.3%;
