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: Currently, the focus of preauricular sinus surgery is on reducing recurrence rates, with limited research on achieving favorable cosmetic outcomes. This study aimed to evaluate the feasibility of retrograde resection of preauricular sinus via the posterior crus of helix approach (PoCHA). Methods: A prospective study was conducted, planning to perform retrograde resection of the preauricular sinus via the PoCHA between January 2025 and April 2025. In the PoCHA, an operative incision was made 2 mm posterior to the posterior edge of the crus of the helix. After excision of the sinus from the spine of the helix cartilage, the sinus tract was separated in a retrograde manner toward the sinus orifice and completely removed. The length of the sinus scar, operation time, postoperative bleeding rate, incision infection and healing rates, scar score, and recurrence rate were evaluated. Results: A total of 40 patients were enrolled. The operation time was 39.92 ± 10.13 minutes. The length of the sinus orifice incision ranged from 0.2 to 0.4 cm, with an average of 0.2 ± 0.004 cm. The postoperative bleeding rate was 5% (2 of 40), the incision infection rate was 2.5% (1 of 40), and the recurrence rate was 0% (0 of 40). The scar score was 0.09 ± 0.34. Conclusions: Retrograde resection of preauricular sinuses via the PoCHA contributes to achieving both radical treatment and favorable cosmetic outcomes, representing a worthwhile surgical option.
