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: This study primarily aimed to evaluate the effects of a hydrogel spacer (HS) on dosimetric distribution in the planning target volume as well as on rectal and urethral doses in high-dose-rate brachytherapy (HDR-BT) for prostate cancer, and to identify prostate sub-regions with improved dosimetric parameters and patient conditions that particularly benefit from the use of HS. Material and methods: This study included 28 patients, who underwent HDR-BT using HS. Treatment plans with HS and simulated plans without HS were compared. The prostate was divided into six regions: ventral and dorsal in the dorsoventral direction, and apex, mid-gland, and base in the craniocaudal direction. V Results: HS significantly improved V Conclusions: HS effectively reduced rectal doses and improved V
