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
Purpose: Both acne keloidalis nuchae (AKN) and cutis verticis gyrata (CVG) are scalp conditions predominantly affecting men. Both are characterized by dermal thickening and fibroblast hyperactivity. AKN typically occurs in the nuchal area, often involving the naturally occurring folds in the occipital region. The aim of this study was to determine the relationship between excessive scalp folding (CVG) and AKN. Patients and methods: A total of 108 patients with AKN seen over 11 years from July 2009 and November 2020 were retrospectively evaluated. Patients with AKN concomitant with CVG were selected for analysis. Results: Seven of the 108 AKN patients had scalp-wide (widespread) AKN lesions, including 4 with CVG. In 3 of the 4 patients with concomitant AKN and CVG, the AKN was widespread, and its onset had preceded CVG by 1-2 years. In the fourth CVG patient, AKN lesions were confined to the nuchal area, and the CVG preceded AKN onset by several years. All patients were male, with a mean age of 35.8 years (overall) and 38.0 years (CVG group). Conclusion: We describe a previously unreported relationship between widespread AKN and CVG, with the development of AKN preceding CVG formation.
