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

BACKGROUND/

aimThis study assessed the positional detection accuracy of the Catalyst MATERIALS AND

methodsAn anthropomorphic head phantom was used to simulate three head postures, chin-up, neutral, and chin-down, each stabilized with a corresponding thermoplastic mask. Seven isocenter positions were defined: one central position and six offset positions, each 5 cm away in a cardinal direction. Treatment plans incorporated multiple couch angles (0°, 30°, 45°, 60°, and 90°). The Catalyst

resultsUnder standard conditions (neutral posture, central isocenter, and 0° couch angle), the system demonstrated submillimeter accuracy (mean translational error: 0.08 mm; mean rotational error: 0.12°). Detection errors were significantly larger in the chin-up posture compared to the neutral posture (
