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

Root canal system variations can occur in each tooth group and significantly influence the outcome of the endodontic treatment. Upper first molars often present with some variations, mostly due to the presence of a second mesio-buccal root canal. Other types of atypical root canal system anatomy in upper first molars have also been reported but with a significantly smaller frequency. The aim of this article is to describe a clinical case of a C-shaped root canal configuration in a maxillary first molar - the diagnosis, preparation, irrigation, and final definitive obturation of the root canal system.
