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: Customized post-and-core restorations can be fabricated using direct or indirect workflows, combined with conventional casting or digital techniques, including milling and selective laser melting (SLM). However, evidence on how these approaches influence apical gap, adaptation, and trueness remains limited. This study aimed to evaluate these outcomes in direct and indirect post-and-core restorations fabricated by casting, milling, and SLM. Methods: Eighty-four mandibular molar post-and-core restorations were fabricated in six groups ( Results: For apical gap, fabrication technique had no significant effect within either workflow (direct: Conclusions: Both fabrication technique (casting, milling, and SLM) and method (direct and indirect) affected apical gap, adaptation, and trueness. The most favorable combinations were direct casting and indirect SLM.
