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

IntroductionDespite technological advances in radiotherapy, trismus persists as a treatment-limiting toxicity in T3-T4 nasopharyngeal carcinoma (NPC) survivors, with current guidelines lacking evidence-based dose constraints for masticatory muscle sparing. This study aimed to establish dose-response relationships and propose clinically actionable thresholds for trismus prevention using volumetric modulated arc therapy (VMAT) with collapsed cone convolution (CCC) dose calculation.MethodsIn this retrospective cohort study, 60 T3-T4 NPC patients treated with VMAT (CCC algorithm) were stratified by trismus severity. Dosimetric parameters (Dmean/Dmax) of jaw-opening (digastric, mylohyoid, geniohyoid) and closing muscles (masseter, pterygoids) were analyzed. Univariate (t-tests) and multivariable logistic regression identified predictors; ROC curves determined optimal dose constraints.ResultsUnivariate analysis: digastric Dmean showed the strongest association with trismus (p = .0049), followed by mylohyoid Dmean (p = .088) and masseter Dmean (p = .063). Multivariable analysis: digastric Dmean retained marginal significance (β=-1.58 × 10
