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

Objective: Dental prostheses are often removed before radiotherapy due to metal-induced artifacts, impairing patients' quality of life. This study evaluated five non-metallic materials for fixed prostheses in head and neck radiotherapy. Methods: Full crowns made of zirconia, lithium disilicate glass-ceramic, resin-matrix ceramic, PEEK, and PMMA were placed on an Results: Artifact reduction significantly altered dose distributions for all materials (P < 0.001). Without artifact reduction, only zirconia differed from natural teeth (P < 0.001). After artifact reduction, no material showed significant difference from the control. Artifact-induced dose error was largest for zirconia, followed by resin-matrix ceramic and glass-ceramic, while errors for PEEK and PMMA were negligible. Conclusion: Zirconia is unsuitable due to severe artifacts. PEEK and PMMA are recommended for provisional crowns. Lithium disilicate glass-ceramic and resin-matrix ceramic are suitable for definitive restorations in radiotherapy patients.
