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

To evaluate the effects of photon beam energy on region-specific scalp dose and target coverage in whole-brain radiotherapy (WBRT), with additional assessment of field configuration. This study was conducted as a benchmark dosimetric investigation using an anthropomorphic head phantom. WBRT plans were generated with a field-in-field technique and lateral opposed fields. Photon beam energies of 4, 6, 8, 10, and 15 MV were assessed under two field configurations: an open-field plan and a close-field plan without air space. The scalp was segmented into four anatomical regions. Dosimetric evaluation included planning target volume coverage, homogeneity index, scalp D
