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

aimThis study aimed to evaluate the reliability and agreement of a semi-automated evaluation of the electronic cast-radiograph evaluation (E-CRE) model score, as developed by the American Board of Orthodontics (ABO), compared to manual measurements.

methodsA total of 67 study models of patients who had completed orthodontic treatment were available, both as digital scans and as plaster models. Manual and digital evaluations followed the E‑CRE guidelines, assessing six criteria: alignment, marginal ridges, buccolingual inclination, occlusal relationships, overjet and root angulation, which was assessed visually on panoramic radiographs. The digital models were graded using a semi-automated software tool in OnyxCeph

resultsThe interobserver reliability was excellent for digital measurements (intraclass correlation coefficient [ICC] 0.94-1.00) and higher compared to those for manual measurements (ICC 0.90-0.97). The reliability between digital and manual measurements was very high, with correlation coefficients ranging from 0.95 to 0.99. However, the digital evaluation produced slightly higher scores for alignment than the manual measurement (mean difference: +0.93).
