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

The understanding of morphological variations in the canal along with the ability to detect and manage the root canal system are essential for achieving a satisfactory endodontic treatment outcome. This case report presents the endodontic management of a C-shaped maxillary second molar with five canals. Cone-beam computerised tomography coupled with a dental operating microscope exhibited remarkable efficacy in the diagnosis, detection and treatment of this irregular morphological root canal system. Clinicians should be alert to anatomic variations in C-shaped maxillary molars during endodontic treatment, even though these variations rarely occur.
