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
purposeWe examined whether false lumen-origin segmental arteries (SAs) were associated with postoperative spinal cord injury (SCI) after surgery for acute Stanford type A aortic dissection (ATAAD).
methodsWe reviewed 201 consecutive patients who underwent open repair for ATAAD between January 2008 and February 2026. After prespecified exclusions, 124 patients were analyzed, including 83 with evaluable contrast-enhanced computed tomography for detailed SA assessment.
resultsPostoperative SCI occurred in 9 patients (7.3%), who comprised the SCI group; the remaining 115 comprised the non-SCI group. Total arch replacement and frozen elephant trunk use were numerically more frequent in the SCI group. In the detailed cohort, the number of false lumen-origin SAs was higher in the SCI group at T3-T7 (7.2 ± 3.0 vs. 3.9 ± 3.1, P = 0.042) and T8-L2 (10.3 ± 2.7 vs. 5.5 ± 4.2, P = 0.005). The corresponding proportions were also higher at T3-T7 (77.5% vs. 45.2%, P = 0.047) and T8-L2 (75.0% vs. 41.9%, P = 0.010).
conclusionIn this exploratory single-center cohort, false lumen-origin SAs were associated with postoperative SCI in unadjusted analyses. Further studies are needed to determine their value for preoperative risk stratification.
