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

Sunburn causes inflammation, which increases melanin production in skin and causes hyperpigmentation. Angiopoietin-like protein (ANGPTL) 2 is an inflammatory mediator induced in sun-exposed skin areas. However, whether ANGPTL2 functions in melanin production remains unclear. To assess this possibility, we overexpressed Angptl2 in the melanoma line B16 and in the keratinocyte line HaCaT. Relative to controls, Angptl2-expressing B16 cells produced higher melanin levels via tyrosinase induction. Accordingly, Angptl2-expressing HaCaT cells secreted relatively high levels of both endothelin-1 (ET-1) and α-melanocyte-stimulating hormone (α-MSH). Moreover, treatment with an extract from Chrysanthemum indicum × Erigeron annuus (CE) suppressed ANGPTL2 expression and repressed tyrosinase induction in melanocytes and of α-MSH and ET-1 in keratinocytes. Our data suggest that ANGPTL2 expression in keratinocytes and melanin-producing cells accelerates pigment production and that treatment of skin with a CE extract could prevent melanin accumulation.
