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
backgroundPaediatric patients undergoing stem cell and gene therapy frequently experience nutritional challenges. Although nutritional status is known to correlate with outcomes, there is no scoring index to quantify the intensity and duration of dietetic interventions in children. We developed a nutritional intensity score that assigns weighted values to different nutritional support strategies that reflects both intervention type and duration over the first 100 days post-transplant.
methodsWe retrospectively analysed 131 paediatric patients after transplant or gene therapy. Nutritional interventions were categorised into five levels: routine dietetic review (1 point), oral nutritional support (2 points), enteral nutritional support (4 points), parenteral nutritional (PN) support (6 points), and bespoke PN support (7 points). The cumulative nutritional intensity score was calculated by multiplying the intervention points by the duration (in days) and summing across all interventions. Subgroup analyses compared median area under the curve (AUC) values in different groups. A further multivariate logistic regression was employed to assess predictors of ≥ PN need at Day 100 within the allogeneic group.
resultsNutritional intensity varied with different treatment modalities. Chimeric Antigen Receptor T-cell (CAR-T) patients showed notably lower median nutritional intensity score (53.0, 95% CI: 30-117) relative to allogeneic (326.0, 95% CI: 282-404) or stem cell gene therapy (124.5, 95% CI: 56-182, p < 0.05) recipients. Within the allogeneic group (n = 109), patients with malignant diseases had a median nutritional intensity score of 444.0 (95% CI: 350.0-466.0) compared to 261.5 (95% CI: 224.0, 322.0, p < 0.01) in those with nonmalignant conditions. Those receiving total body irradiation (TBI) had higher median nutritional intensity score values (476.0, 95% CI: 317-543) than those without TBI (302.0, 95% CI: 244-386; p < 0.01). In the multivariate analysis, higher nutritional intensity score, malignant disease status, and TBI were significant predictors of ≥ PN requirement at Day 100.
conclusionOur nutritional intensity score reflects the cumulative burden of nutritional interventions in paediatric patients, and will inform patient and service planning. Future prospective studies are required to validate its predictive value.
