In vitro comparison of marginal fit between CAD/CAM hybrid ceramic crowns and prefabricated zirconia crowns for primary molars.

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
This study aimed to compare the marginal fit of the hybrid ceramic Vita Enamic (VE) crown fabricated with CAD/CAM versus prefabricated zirconia crown (PZC). An in vitro study was conducted on fifty epoxy resin replicas of 25 standardly prepared mandibular second primary molars (2 replicas for each tooth) were obtained. One tooth was restored with CAD/CAM VE (Zahnfabrik, H. Rauter GmbH & Co. KG) after an optical impression acquired using CEREC Omnicam and the other tooth restored with PZC (NuSmile, Houston, TX, USA). Specimens were sectioned buccolingually and mesiodistally. The marginal fit average was measured using a scanning electron microscope (SEM). The difference was tested for statistical significance using an independent t test at a 5% significance level and 95% CI. CAD/CAM VE crowns showed superior marginal adaptation over the PZCs with a significant difference. The mean difference at the buccolingual section was -10.52 µm with a 95% CI of -20.99; -0.05 (P = 0.049). At the mesiodistal section, the mean difference was -10.56 µm with a 95% CI of -20.82; -0.30 (P = 0.044).VE provides a superior marginal fit over the PZC in the restoration of primary molars.
