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

background and purposeHair follicle telogen to anagen transition results in a break in cellular quiescence of the hair follicle stem cells, which subsequently promotes hair follicle regeneration. Many critical molecules and signalling pathways are involved in hair follicle cycle progression. Transient receptor potential vanilloid 4 (TRPV4) is a polymodal sensory transducer that regulates various cutaneous functions under both normal and disease conditions. However, the role of TRPV4 in hair follicle regeneration in vivo remains incompletely understood. EXPERIMENTAL APPROACH: Using adult C57BL/6J mice, keratinocyte (K14 KEY

resultsHere, we show that a single intradermal injection of GSK1016790A is sufficient to induce telogen to anagen transition and hair follicle regeneration in mice by increasing the expression of the anagen-promoting growth factors and down-regulating the expression of growth factors that inhibit anagen. The action of GSK1016790A relies largely on the function of TRPV4 in skin and involves activation of downstream ERK signalling. CONCLUSION AND IMPLICATIONS: Our results suggest that transient chemical activation of TRPV4 in the skin induces hair follicle regeneration in mice, which might provide an effective therapeutic strategy for the treatment of hair loss and alopecia.
