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
Post plays a crucial role in reinforcing final restoration in endodontically treated teeth (ETT). The appropriate selection of the post system is crucial for enhancing the clinical success of the restored tooth. This study aims to evaluate the adaptation, fracture resistance, and fracture patterns of ETT restored with different post systems, specifically zirconia posts, cast metal posts (CMP), and anatomically customised fibre-reinforced composite (FRC) posts. Twenty-four human premolars were randomly allocated into four groups. The teeth were root canal treated and prepared to receive zirconia, CMP, and anatomically customised FRC posts. All the samples were subjected to adaptation evaluation, fracture resistance test, and fracture pattern analysis. One-way ANOVA showed a statistically significant difference in mean adaptation between the groups (p < 0.001). Post-hoc Bonferroni analysis suggested that the adaptation values were statistically significant among zirconia and CMP (p < 0.001), and in zirconia and FRC (p = 0.007). Regarding fracture resistance, one-way ANOVA presented a statistically significant difference among the groups (p = 0.001). Post-hoc Bonferroni analysis reported a significant difference in fracture resistance in zirconia and control (p = 0.001), CMP and FRC (p < 0.001), and FRC and control. The categorical analysis of fracture patterns revealed no statistically significant differences among the zirconia, CMP, and FRC post systems. Zirconia posts show lower adaptation than CMP and FRC posts. However, their fracture resistance is comparable to CMPs and FRCs. Fracture patterns were generally consistent across the different post systems; however, the control group exhibited a significantly different pattern, highlighting the influence of post presence on fracture behaviour.
