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

Accurate digital impressions are crucial in modern dentistry, particularly for capturing fine details of various dental preparations. This study aimed to evaluate the effect of variations in the sizes of crown and inlay specimen on the accuracy of three digital impression techniques. Nine crown and nine inlay specimens were fabricated according to American Dental Association Standard No. 132. Gold standard measurements were obtained using a coordinate-measuring machine. Digitized files were generated using three impression techniques (n = 10): intraoral scanner (IOS), extraoral scanner with alginate (EOS-A), and extraoral scanner with silicone rubber (EOS-S). Digital models from EOSs served as reference sets for three-dimensional (3D) fitting analysis. Statistical analysis was conducted using one-way analysis of variance and Tukey's post-hoc test. Specimen size variations significantly affected the accuracy of all impression techniques (p < 0.05). IOS exhibited superior accuracy across all specimens, with most trueness values falling within the clinical threshold. EOS-S demonstrated moderate trueness, meeting the threshold for most indexes, except the r
