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 primary aim of this study was to demonstrate the benefits of topical human platelet exosome extract (HPE) (plated) hair serum for improving hair and scalp health in participants with self-perceived thinning hair. Methods: This single-center, placebo-controlled, double-blind study enrolled 39 healthy men and women 18-65 years of age with self-perceived thinning hair. Participants applied either HPE for 9 months or a topical placebo for 6 months with the option to cross over to HPE at 6 months for an additional 3 months. End points included improvements in the global aesthetic appearance of hair, as assessed by a blinded live evaluator; participant-reported outcomes; hair trichoscopy; and independent physician photograph evaluations. Safety data included monitoring for adverse events. Results: Blinded live evaluator assessments demonstrated statistically significant improvements in the global aesthetic appearance of hair for volume/fullness, density, scalp coverage, and appearance, with all Conclusions: This study demonstrates that topical HPE (plated) hair serum with Renewosome technology significantly improves hair and scalp health and is safe and well tolerated.
