1 · What the graph read from it

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.

2 · The registry

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

Serotonin (5-hydroxytryptamine, 5-HT) is a neurotransmitter that plays a vital role in regulating behavior, mood, memory, and gastrointestinal homeostasis. Although recent studies have identified an intestine-hair follicle link, potentially implicating 5-HT, its exact relationship with hair growth remains unclear. Here we investigated the effects of serotonin signaling on hair follicle homeostasis. Gene expression analysis showed significant upregulation of hair growth-related genes in dermal papilla cells treated with 5-HT. The hair growth-promoting effects of 5-HT were examined using hair follicle organoids and hair follicle organ cultures. The addition of 5-HT to hair follicle organoids and hair follicles promoted hair shaft elongation. Similar effects were observed with sumatriptan succinate, a 5-HT receptor agonist. These results suggest that targeting serotonin signaling can advance alopecia therapy.
