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

Background: The objective of this study was to assess the push-out bond strength (PBS) of conventional prefabricated, universal 2-piece, and CAD/CAM-milled fiber posts cemented in root canals using a self-adhesive resin cement, as well as the Vickers microhardness (VHN) of the resin cement. Material and Methods: Thirty human uniradicular premolars roots were endodontically treated and divided into three groups (n = 10): conventional prefabricated fiber posts (PFPs), universal fiber posts (UFPs), and CAD/CAM-milled fiber posts (MFPs). After luting procedures using RelyX U200 (Solventum), six specimens were obtained of each root (two slices from each root third: cervical, middle, and apical). The first slices of each root region were subjected to PBS, and the second slices were subjected to VHN analysis. Data from the PBS and VHN tests were analyzed using two-way analysis of variance (ANOVA; post type vs. root region) and Tukey's test (α = 0.05). Results: Regarding the PBS, MFPs and UFPs demonstrated statistically superior performance than PFPs ( Conclusions: CAD/CAM-milled and universal 2-piece fiber posts may be a better alternative for restoring widened root canals.
