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
Purpose: Intraluminal gas in rectum can be observed in some cervical cancer patients who underwent brachytherapy, leading to increased rectal volume. This might increase radiation dose to the rectum, and result in rectal complications. The aim of the study was to investigate the effect of intrarectal gas drainage by rectal catheterization using Foley catheter on rectal dimensions, target dose, and adjacent organs at risk (OARs) doses in cervical cancer patients treated with image-guided adaptive brachytherapy. Material and methods: Computed tomography (CT) images before and after rectal gas drainage were retrospectively collected from 20 brachytherapy sessions of 17 cervical cancer patients, who received image-guided adaptive brachytherapy from January 2018 to May 2019 at a single institution. Target volume and adjacent OARs were delineated, and brachytherapy planning was performed using both CT images. Rectal diameter from 2 cm above to 2 cm below cervical os were measured. Dosimetric comparison between pre-procedural and post-procedural plans was performed. Results: Rectal medio-lateral diameter at multiple levels was significantly decreased after rectal gas drainage, while rectal antero-posterior diameter only at 1 cm above cervical os was significantly decreased after the procedure. The calculated dose to high-risk clinical target volume (HR-CTV) and the bladder dose was comparable before and after the procedure. However, significant reductions in rectal D Conclusions: Intrarectal gas reduction by rectal catheterization with Foley catheter can significantly reduce rectal distention in lateral dimension and improve rectal dosimetric parameters. This procedure can be used in patients with remaining intraluminal rectal gas after patient rectal self-preparation to minimize rectal toxicity.
