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
Background: The superimposition in radiographic images makes it difficult to diagnose C-shaped canals using two-dimensional imaging techniques. A non-invasive technique called cone-beam computed tomography (CBCT) makes it easier to comprehend the C-shaped canal architecture along the root. Aim: This study was undertaken to evaluate C-shaped canals in permanent second molars of mandible in a Saudi Arabian subpopulation using CBCT. Methods: This research was a non-interventional, retrospective clinical trial. CBCT images of 452 mandibular second molars were selected from 300 patients. Every CBCT scan was interpreted by a certified oral radiologist to gather information regarding root canal anatomy, configuration, location, etc. Results: The C-shaped canal was present in 51 (11.28%) of the 452 teeth. The C2 configuration was found to be the most common (28 teeth, 6.19%) followed by C3 (15 teeth, 3.31%), and C1 (7 teeth, 1.54%). Only one tooth (0.22%) had the C5 configuration, and none had the C4 configuration. The C-shaped canal was present in 35 (13.46%) of the 260 teeth from female patients and in 16 (8.33%) of the 192 teeth in male patients ( Conclusion: The overall prevalence of C-shaped canals in mandibular second molars was 11.28% in Saudi population. This arrangement was more common in women than in men.
