Assessing the impact of nutritional status at allogeneic stem cell transplantation on clinical outcomes.

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
purposeNutritional status at allogeneic hematopoietic cell transplantation (HCT) can significantly impact outcomes, but conflicting results are reported.
methodsWe investigate the role of nutritional status on HCT outcomes in 158 patients, including diabetes, body mass index (BMI), nutritional risk index (NRI) and the patient-generated subjective global assessment (PG-SGA).
resultsPG-SGA was scored as A (well nourished) in 52%, B (risk of malnutrition or moderate malnutrition) in 44% and C (severely malnourished) in 4%. NRI was mild in 14 (9%), moderate in 33 (21%) and severe in 4 (3%) patients. Oral nutritional support and total parenteral nutrition was used during hospitalization in 86% and 36% patients. The cumulative incidence of grade II-IV acute graft-versus-host disease (GvHD) at 100 days was 20% (95% CI 14-27%). At 30 months, chronic GvHD was 17% (95% CI 12-24%), non-relapse mortality (NRM) was 25% (95% CI 19-33%) and relapse incidence (RI) was 24% (95% CI 18-32%). Overall survival and progression-free survival were 57% (95% CI 49-64%) and 50% (95% CI 42-58%) at 30 months. Patients with a median BMI above the median (median BMI = 25.87 kg/m2) had a lower risk of both acute (HR 0.42, 95%CI 0.12-0.92, p = 0.03) and chronic (HR 0.42, 95%CI 0.19-0.90, p = 0.02) GvHD in multivariate analysis. No statistical differences were found according to PG-SGA and NRI.
conclusionsOur findings highlight the critical role of pre-transplant metabolic evaluation, personalized nutritional support, and optimal glycemic regulation in HCT care. Further large-scale studies are required to determine the association between nutritional status and HCT outcomes.
