Pretransplant Minimal Pleural and Peritoneal Effusion Is a Potential Poor Prognostic Indicator in Allogeneic Hematopoietic Stem Cell Transplantation.
Article in Clinical transplantation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPleural effusion and ascites developing after allogeneic hematopoietic stem cell transplantation (allo-SCT) are generally associated with inferior overall survival (OS); however, the prognostic value of pretransplant effusion on transplant outcomes remained unclear.
methodsWe retrospectively evaluated minimal pleural effusion and ascites detected by computed tomography in 248 consecutive adult patients who underwent their first allo-SCT from January 2007 to December 2022.
resultsForty-eight patients demonstrated minimal pleural effusion or ascites within 100 days before transplantation (Effusion group) and the other 200 had no effusion (No effusion group). Serum albumin level was significantly lower in the Effusion group than in the No effusion group (median 3.8 vs. 3.4 g/dL, p < 0.001). Performance status (PS) was significantly inferior and refined disease risk index tended to be higher in the Effusion group. The 2-year OS rate after transplantation was significantly worse in the Effusion group (57.1% vs. 36.7%, p < 0.001). The Effusion group had a significantly lower cumulative incidence of neutrophil and platelet engraftment and higher hepatic veno-occlusive disease. Moreover, a tendency toward higher cumulative incidence of relapse and non-relapse mortality was shown in the Effusion group. In multivariate analysis, the Effusion group had a significantly inferior OS with a hazard ratio of 1.848 (95% confidence interval 1.231-2.774), even after adjustment for disease risk, serum albumin level, PS, and Hematopoietic Cell Transplant-Comorbidity Index points.
conclusionReflecting high disease activity and impaired general condition, pretransplant effusion can be a complementary indicator for poor prognosis in allo-SCT.
