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
backgroundHigh-grade squamous intraepithelial lesions (HSIL) of the anal region are recognized as precursor lesions to squamous cell carcinoma of the anus (SCCA), especially in individuals infected with the human papillomavirus (HPV). Although recent studies indicate that treating HSIL can reduce progression to SCCA, optimal management strategies remain undefined. High recurrence rates and treatment-associated morbidities underscore the need for effective therapeutic options.
methodsA survey among radiation oncologists in Germany was conducted between September and October 2024, covering clinical practice settings, the frequency of HSIL cases, experience with radiotherapy, reasons for radiotherapy inquiries, treatment indications, and concurrent therapies.
resultsA total of 58 radiation oncologists participated in the survey, with 37 (63.8%) reporting inquiries about radiotherapy for HSIL, primarily for patients with multiple recurrences. Radiotherapy was generally considered an appropriate option, particularly for recurrent cases where other treatments posed risks, especially complications or worsening of anorectal function after local excision. However, only half of the respondents (29) had prior experience with treating anal HSIL and rated radiotherapy outcomes as good or very good. Most respondents indicated a preference for treating only the local area (i.e., excluding lymphatic drainage pathways) to a total dose of 40-50 Gy.
conclusionRecurrent anal HSIL presents a major challenge for patients, with no established effective treatment standards available. Radiotherapy is frequently requested and administered, showing promising preliminary outcomes. Clinical studies are warranted to evaluate the effectiveness and tolerability of radiotherapy in patients with anal HSIL.
