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: The 30-day Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) has been used to risk-stratify patients undergoing transcatheter aortic valve replacement (TAVR). Whether surgical mortality risk predicts stroke and neurocognitive outcomes following TAVR is unknown. We evaluated the association between STS-PROM and clinical outcomes, including stroke, acute brain injury on diffusion-weighted magnetic resonance imaging (DW-MRI), and cognitive decline in patients undergoing TAVR. Methods: Patient-level data were pooled from 4 prospective trials: (1) DEFLECT III (N = 87), (2) NeuroTAVR (N = 44), (3) REFLECT I (N = 214), and (4) REFLECT II (N = 258). All studies included patients undergoing TAVR with a protocol-mandated predischarge DW-MRI and serial cognitive and neurologic assessments. All patients were evaluated by a board-certified neurologist at baseline, postprocedure, and 30 days. Clinical outcomes, including stroke, cognitive decline (Montreal Cognitive Assessment score), death, myocardial infarction, vascular, and bleeding complications were adjudicated by the same clinical events committee. Imaging analysis was performed by a single core laboratory using identical methods. The DW-MRI measures included total lesion number, individual lesion volume, and total lesion volume. Outcomes were compared between low (STS <4), intermediate (STS 4-8), and high (STS >8) risk groups. Results: In total, 537 of 603 patients with DW-MRI and complete STS assessment undergoing transfemoral TAVR were included in this pooled analysis, of which 253 (47%) were low risk, 198 (37%) intermediate risk, and 86 (16%) high risk patients. At 30 days, high risk patients had higher rates of all-cause and cardiovascular mortality, myocardial infarction, acute kidney injury, bleeding, and vascular complications. Rates of stroke, disabling stroke, DW-MRI measures of brain injury, and cognitive decline were similar across risk categories. Conclusions: This pooled analysis demonstrates that the STS score does not predict stroke, cognitive decline, or acute brain injury after TAVR.
