Risk factors associated with chronic cutaneous graft-versus-host disease following hematopoietic stem cell transplantation: a pediatric cohort.

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
backgroundGraft-versus-host disease (GVHD) is a frequent complication of hematopoietic stem cell transplantation (HSCT), with the skin being the most commonly affected organ. However, its risk factors remain poorly defined.
objectiveTo assess the risk factors associated with chronic cutaneous GVHD (ccGVHD) in a children's hospital in Chile.
methodsThis retrospective cohort study examined children under 18-years who underwent HSCT between 2007 and 2017, with a follow-up period of at least 2-years. Survival analysis and Cox regression analysis were performed.
results150 children with HSCT were included with a median age of 7.3 (3.7‒10.6) years. 17.3% of the children developed ccGVHD, with a median onset after HSCT of 8 (4‒11) months. In the univariate analysis, patients with ccGVHD were significantly older at transplantation, with a higher proportion of bone marrow as graft source, related donor, and acute GVHD compared to those who did not develop ccGVHD (for all p < 0.05). In the multivariate analysis, the main risk factors were male sex (Hazard Ratio [HR] 2.51), total body irradiation as conditioning regimen (HR = 3.53), and bone marrow as graft source (HR = 7.28). STUDY LIMITATIONS: Its retrospective, single-center design may reduce generalizability and introduce selection bias.
conclusionsThis study is one of the largest series of ccGVHD in children. Early identification of patients at higher risk of ccGVHD allows for timely initiation of treatment, thereby reducing the morbidity associated with this debilitating complication.
