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
Aim: This study aims to compare the fracture resistance of simulated immature teeth after using different thicknesses of Mineral Trioxide Aggregate (MTA) and Biodentine apical plug. Materials and Methods: Forty human maxillary anterior teeth were selected. Teeth were randomly divided into eight groups of five teeth in each group. Positive control group = 5 teeth; prepared without access cavity preparation. Access cavities of the remaining 35 teeth were prepared, and instrumented with Peeso reamers. Negative control = 5 teeth; filled with calcium hydroxide. Thirty teeth divided into Groups 1 and 2 of MTA (MTA-Angelus, Londrina, Brazil) and Biodentine (Septodant, Saint Maur des Fosses, France) and each group divided into three subgroups: subgroup A - 3 mm apical plug; subgroup B - 6 mm apical plug; and subgroup C: full canal length. The rest of the canals in subgroups A and B were filled with gutta-percha and AH Plus sealer. After the required storage period, all the samples were subjected to fracture testing under universal testing machine and fracture strength was recorded. Data were analyzed using 1-way analysis of variance with the Tukey post hoc test for multiple comparisons. Results: The negative control group showed the lowest fracture resistance compared with the other groups (P < 0.0001). The 6-mm apical plug subgroup of biodentine showed the highest fracture resistance. Conclusion: Within the limitations of this study, MTA and Biodentine can be used as an apical plug instead of root canal filling material to increase the fracture resistance of immature teeth.
