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

Alopecia areata (AA) is an autoimmune non-scarring hair loss that arises in genetically susceptible individuals, potentially in combination with environmental triggers or inciting events, of which the exact mechanism is not yet fully understood. Genome wide association studies have demonstrated an association between AA and variants in HLA haplotypes on chromosome 6 which correlate with other autoimmune conditions as well as other gene variants. Familial and twin studies also confer additional evidence to a genetic component. AA pathogenesis relies on immune privilege collapse at the hair follicle (HF) bulb in the anagen hair cycle phase. Immune privilege collapse is associated with upregulation of IFN-γ, ultimately activating JAK-STAT pathway resulting in upregulation of MHC class I and II in the HF and subjecting it to attack by NKG2D
