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

objectivesTo evaluate the influence of different spatial scanning resolutions of photostimulable phosphor (PSP) plates on digital radiographic images using texture analysis (TA). MATERIALS AND

methodsDigital radiographs of an aluminum step wedge with five steps (0.5 mm increments) were acquired at two radiographic exposure times (0.10 and 0.20 s). Each image was scanned at four different spatial resolutions (10, 20, 25, and 40 lp/mm), with 10 repetitions per condition. Regions of interest (ROIs) were placed on the steps with thicknesses of 0.5, 1.5, and 2.5 mm. Texture features based on the gray-level co-occurrence matrix (GLCM) were extracted using MaZda 4.6 software. Exploratory data analysis was performed, and spatial resolutions were compared within each combination of exposure time and object thickness using ANOVA, followed by Tukey's post-hoc test (p < 0.05).

resultsAt 0.10 s exposure, eight texture parameters exhibited statistically significant differences among spatial resolutions, independent of object thickness, with higher values observed at 10 and 20 lp/mm. For an exposure of 0.20 s, two parameters also showed significant differences across resolutions, with higher values at lower resolutions.

conclusionsTA revealed that, in the tested PSP system, lower scanning resolutions resulted in images with reduced homogeneity and uniformity, regardless of object thickness.
