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
purposeThe purpose of this study was to investigate the feasibility and effectiveness of high-dose planned adaptive intensity-modulated radiation therapy (IMRT) with helical tomotherapy (HT) for cutaneous angiosarcoma (cAS) of the scalp.
methodsThis retrospective cross-sectional included a total of 12 consecutive patients with cAS of the scalp who underwent high-dose planned adaptive IMRT with HT. Prescribed doses were 72.5-74 Gy in 35-37 fractions for the gross tumor volume plus a 1-2 mm margin (PTV1), 58-60 Gy in 29-30 fractions for the clinical target volume plus a 2-3 mm margin (PTV2), and 46 Gy in 23 fractions for the clinical target volume plus a 5-15 mm margin (PTV3) over periods of 7.5, 6 and 4.5 weeks, respectively.
resultsThe estimated 1‑year and 2‑year overall survival rate were 65.6% and 27.3%, respectively, and the local progression-free survival at 2 years was 74.1%. All local recurrences were either in or marginal to the PTV2 or PTV3. No local recurrence was observed in the PTV1. All patients tolerated the treatment without grade 3 or higher adverse events during the radiotherapy period. No late adverse events were observed during the follow-up period.
conclusionPlanned adaptive high-dose IMRT with HT has the potential to improve local control rate without increasing adverse events.
