Risk factors for alloimmune lung syndromes after allogeneic hematopoietic cell transplantation in children.

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
The non-infectious pulmonary complications idiopathic pneumonia syndrome (IPS) and bronchiolitis obliterans syndrome (BOS) are important causes of morbidity and mortality after allogeneic hematopoietic cell transplantation (allo-HCT). To identify risk factors for these complications, we retrospectively analyzed baseline characteristics and longitudinal data from 633 pediatric and young adult allo-HCT recipients. Risk factors for IPS included non-malignant diagnosis (HR 2.97; 95% CI 1.27-6.97; P = 0.01) and adenovirus reactivation (HR 2.75; 95% CI 1.24-6.14; P = 0.01). Conditioning with busulfan-cyclophosphamide ±melphalan (BuCy ±Mel) associated with increased IPS risk compared to busulfan-fludarabine ±clofarabine (HR 5.15; 95% CI 2.36-11.24; P < 0.001) and non-myeloablative regimens (HR 9.78; 95% CI 2.48-38.61; P = 0.001). BuCy ±Mel conditioning also related to increased BOS risk relative to total body irradiation (TBI)(HR 5.11; 95%CI 1.65-15.83; P = 0.005) and non-myeloablative regimens (HR 19.68; 95% CI 2.53-155.76; P = 0.005). Moreover, elevated endothelial activation and stress index (EASIX), white blood cell, and lymphocyte counts before day 100 post-transplant correlated with IPS. For BOS, high EASIX and increased activated or effector memory CD4 + T-cells were additional significant correlates. In conclusion, IPS and BOS were associated with both distinct and overlapping risk factors in this study. These findings may inform future strategies to identify high-risk patients and develop targeted preventive interventions.
