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.
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
Film quality assurance software is an integral component of patient-specific quality assurance for various radiation techniques where high degrees of geometrical and dosimetric accuracy are required. Evaluating the accuracy of film quality assurance software products has relied on various techniques ranging from comparative analyses, measurements with phantoms and other detectors, along with confidence from industry-standard peer reviews. The aim of this work was to determine if a series of synthetically created film and DICOM images can be used to test the accuracy of certain patient specific quality assurance metrics used in film quality assurance software packages. The synthetic images have been engineered to simulate radiographic film scanned TIFF images and treatment planning system exported DICOM files. Each pair of images were designed to test a particular component of the software's ability to process curve fitting, dosimetric differences, distance to agreement, percentage threshold and gamma analysis. It was found that synthetic film could simulate radiographic scanned films and treatment planning system DICOM planes and provide the physicist with empirical data on the accuracy of the mentioned metrics. The series of tests also assisted the physicist in identifying optimal calibration models, validating geometric and dosimetric variations, and offering insights into potential differences in lower dose penumbras.
