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

The aim of this study was to determine appropriate multileaf collimator (MLC) parameters for the Enhanced Leaf Model (ELM) for the Varian TrueBeam (120 MLC) and to verify the dose calculation accuracy of the ELM in brain stereotactic radiotherapy (SRT). A survey on transmission and dosimetric leaf gap (DLG) values was conducted at five institutions. Dosimetric verification was performed for brain SRT using SRS MapCHECK or Gafchromic film for four targets (0.4-2.8 cm
