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 and Aims: Androgenetic alopecia is the most common cause of hair loss in both men and women. The aim of this case-control study was to investigate the role of phenotype (hair shape, thickness, and color) and demographic characteristics, including smoking history, in the development of androgenetic alopecia. Methods: In this case-control study, participants were divided into two groups: patients diagnosed with androgenetic alopecia (case group) and individuals without hair loss (control group). Data on demographic characteristics (age, gender), hair phenotype (shape, thickness, and color), and smoking history were collected. The case group consisted of individuals diagnosed with androgenetic alopecia at a skin and hair clinic, while the control group included patients visiting the clinic for other skin conditions. Data were analyzed using SPSS software. Results: The study compared data from 50 patients with androgenetic alopecia and 50 control participants. Smoking was found to increase susceptibility to alopecia, and a significant association was observed between lighter hair color and androgenetic alopecia. No significant relationship was found between hair thickness or shape and alopecia. Additionally, women had a higher prevalence of alopecia than men. Individuals with alopecia were significantly older, with a higher frequency of alopecia observed in those over the age of 25 ( Conclusion: Age, hair color, smoking, and gender were found to significantly influence the development of androgenetic alopecia. These findings suggest the importance of considering demographic and phenotypic factors in understanding the pathogenesis of this condition.
