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
purposeReirradiation has the potential to provide effective local control of upper abdominal malignancies. This study aimed to evaluate the safety and efficacy of reirradiation for upper abdominal malignancies.
methodsA total of 42 patients with a history of prior radiotherapy (RT) received reirradiation for abdominal malignancies between 2005 and 2017. Each patient's medical records, contours, and dose distribution for both RT courses were reviewed. The median dose of the prior RT was 50.0 Gy (range, 30.0-60.0 Gy) and the median dose of reirradiation was 45.0 Gy (range, 15.0-75.0 Gy).
resultsWith a median follow-up of 10.9 months, the median infield-failure-free survival (IFFS) rate was 9.2 months. Gross tumor volume (GTV) significantly related to IFFS in both the univariate (p = 0.009) and multivariate analyses (p = 0.024), and patients with a GTV of <60.0 mL had an improved IFFS (p = 0.001). Four patients experienced ≥grade 3 late toxicities. In the retrospective dose reconstruction analysis in these patients, the cumulative dose to the most exposed 2 cc (D2cc) of the duodenum was >60.0 Gy (range, 60.1-73.7 Gy). In the univariate analysis, the D2cc of the duodenum and a preexisting duodenal ulcer identified using endoscopy prior to reirradiation significantly correlated with late severe toxicity (p = 0.021 and 0.017, respectively).
conclusionsReirradiation for upper abdominal malignancies could be safely performed for patients without preexisting gastrointestinal morbidity unless the duodenum received excessive radiation doses. Reirradiation could also provide substantial IFFS, especially for patients with a GTV of <60.0 mL.
