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
abstractAcute graft-versus-host disease (aGVHD) contributes to significant morbidity after allogeneic hematopoietic cell transplantation (allo-HCT). We aimed to develop and validate a clinical score to identify patients with significantly different risk for developing aGVHD. Analysis included adults who underwent allo-HCT during 2008-2019. Eligibility criteria were widely inclusive of transplant indications, donor types, graft types, conditioning regimens, and GVHD prophylaxis regimens. The final cohort of 21 796 patients was randomly split into training and validation cohorts, with 15 258 (70%) and 6538 (30%) patients, respectively. The primary outcome was grade 2 to 4 aGVHD, and the secondary outcome was grade 3 to 4 aGVHD, by day 100 posttransplant. Risk scores were developed using the training cohort, tested using the validation cohort, and stratified into 4 percentile groups. The odds of grade 2 to 4 aGVHD by day 100 posttransplant were 1.50 (95% confidence interval [CI], 1.29-1.75; P< .0001) for the 25th to 50th percentile group, 2.0 (95% CI, 1.78-2.40; P< .0001) for the 50th to 75th percentile group, and 3.1 (95% CI, 2.72-3.65; P< .0001) for the >75th percentile group compared with the ≤25th percentile group in the validation cohort. The odds of grade 3 to 4 aGVHD by day 100 posttransplant were 1.4 (95% CI, 1.11-1.74; P = .0043) in the 25th to 50th percentile group, 2.0 (95% CI, 1.61-2.49; P< .0001) in the 50th to 75th percentile group, and 3.2 (95% CI, 2.64-3.98; P< .0001) in the >75th percentile group compared with the ≤25th percentile group in the validation cohort. Here, to our knowledge, we have developed the first validated, widely inclusive clinical risk score for the development of aGVHD after allo-HCT.
