The "C" in Complexity: A Case Series on Navigating Fan's Classification of C-shaped Canals.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
C-shaped canal anatomy is most commonly found in mandibular second molars. The complex anatomy can be challenging to the clinician during negotiation, debridement, and obturation. The fan-shaped regions, transverse anastomoses, fins, and webs of the C-shaped anatomy can be identified and treated with the help of radiographic and clinical diagnosis. Adequate knowledge of the root canal configuration is essential to achieve success in endodontic therapy. This case series highlights the management of four different cases of C-shaped canal configurations categorized on the basis of Fan's Classification. Despite the significant challenges, a positive outcome was achieved in all the cases through specific protocols and modified obturation techniques.
