1 · What the graph read from it

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.

2 · The registry

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: Brachytherapy applicator selection in the treatment of cervical cancer often relies on intra-operative judgment. Pre-brachytherapy magnetic resonance imaging (pre-MRI) may provide earlier guidance for most appropriate applicator type and size across varying vaginal canal (VC) anatomies. This study investigated the relationship between pre-MRI VC volumes and applicator selection. Material and methods: One hundred and fourteen patients with cervical cancer treated with brachytherapy (2022-2024) were analyzed. Patient and treatment characteristics, including applicator type (tandem and ovoid [TO] vs. tandem and cylinder with needles [TC]), were collected. Pre-MRI with vaginal gel was used for optimal delineation of the upper 1 cm and 2 cm VC volumes, which were then analyzed in relation to applicator type and size selection. Results: Most patients had FIGO stage III-IV (75%) disease. The upper 2 cm VC volume was significantly associated with applicator selection across all fractions, with smaller volumes favoring TC applicators and larger volumes favoring TO applicators ( Conclusions: Pre-MRI VC volume measurements may aid in applicator selection; particularly upper 2 cm volumes < 4 cm
