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

backgroundWe investigate the association of postoperative radiotherapy (PORT) volumes and salivary function in oral cavity SCC (OSCC).

methodsOSCC patients undergoing PORT 2005-2021 underwent modified Schirmer test (MST) pre-PORT, 6 and/or 12 months post-PORT. Hyposalivation rates were compared by PORT volumes. MVA identified predictors for chronic hyposalivation.

resultsAmong 165 eligible patients, 88 (53%) received bilateral, 66 (40%) ipsilateral, and 11 (7%) no-neck (primary-only) PORT. Baseline characteristics were similar, except more N2b/N2c disease received bilateral PORT vs. ipsilateral or no-neck (60% vs. 36% vs. 0%, p < 0.001). Baseline hyposalivation was similar (26% vs. 30% vs. 18%, p = 0.67). Hyposalivation occurred more frequently in bilateral vs. ipsilateral vs. no-neck PORT at 6 (90% vs. 62% vs. 9%) and 12 months (90% vs. 48% vs. 0%) (both p < 0.001). On MVA, bilateral neck PORT and smoking predicted chronic hyposalivation.

conclusionIncreasing PORT volumes predict saliva function recovery and chronic hyposalivation, informing treatment discussions.
