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
Background: Aesthetic restorations for managing severely carious primary molars pose a clinical challenge, particularly regarding limited treatment options and the importance of aesthetics to parents. While zirconia crowns are commonly used for posterior teeth due to their aesthetic appeal, advancements in digital technology have introduced alternative options such as polymethylmethacrylate (PMMA) crowns and 3D printable photopolymer resin crowns, which offer cost-effective alternatives. This in vitro study aimed to comparatively evaluate the fracture resistance force (FRF) and occlusal wear of three types of posterior aesthetic crowns: milled zirconia crowns, PMMA crowns, and 3D printable photopolymer resin crowns. Material and Methods: A universal mechanical testing machine was employed to measure the FRF, while occlusal wear was assessed by subjecting five samples from each group to chewing simulation with opposing natural teeth. Preoperative and post-operative 3D scan measurements were obtained. Results: The average force required to fracture 3D printable photopolymer resin crowns was 877.212 N, compared to 1,326.522 N for PMMA crowns and 1,712.488 N for milled zirconia crowns. Significant differences in occlusal wear were observed in the zirconia ( Conclusions: This study suggests that PMMA crowns exhibit clinically acceptable fracture resistance force and cause minimal occlusal wear on opposing primary teeth. These findings support the potential long-term clinical use of PMMA crowns as an alternative to zirconia crowns in aesthetic restorations for severely decayed primary molars.
