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

objectiveTo analyze and compare the interfractional setup errors between two body positioning fixation methods (lithotomy position with carbon fiber full-body fixation frame

methodsA retrospective analysis was conducted on 37 consecutive patients who underwent radical prostate radiotherapy at Peking University First Hospital between August 2021 and March 2023. The patients were divided into two groups based on the immobilization method: Group A (18 patients, 450 CBCT image sets) used a carbon fiber whole-body fixator in the lithotomy position, while Group B (19 patients, 461 CBCT image sets) used a conventional carbon fiber fixator combined with a thermoplastic mask. All the patients underwent daily cone-beam computed tomography (CBCT) image guidance. Bone registration combined with manual registration was used to obtain the setup error data in the left-right (

resultsThe analysis of the setup errors in the three-dimensional direction showed significant differences between the two groups (all

conclusionConventional carbon fiber human body fixator combined with thermoplastic film can significantly reduce the setup error. However, the carbon fiber whole-body fixator in the lithotomy position demonstrated larger setup errors in the
