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

backgroundThis study comprehensively evaluated the impact of aperture shape controller (ASC) on volumetric modulated arc therapy (VMAT) clinical treatment planning.

methodsA total of 248 VMAT plans for head and neck, prostate, post mastectomy breast, gastric MALT lymphoma, rectum, and Lung SBRT for treatments performed between 2018 and 2023 were retrospectively enrolled. These treatment plans were divided into two groups: before (ASC-OFF group) and after (ASC-ON group) the clinical implementation of ASC. The performance of ASC in terms of plan complexity was evaluated by between group comparisons of the multi-leaf collimator (MLC) modulation complexity score (MCS

resultsThe overall MCS

conclusionsThe use of ASC reduced the complexity of MLC motions without compromising the plan quality. Furthermore, this study found that ASC allows jaw tracking to be more effective.
