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

Toxic metals are not so rare but are often neglected causes of alopecia areata in men and women. Thallium, arsenic, selenium, and mercury are the most common cause of metals-related alopecia, which is what Vicky Yu and colleagues' found. Other than the presence of thallium, arsenic, mercury, and selenium, cadmium, bismuth, lithium, and copper should also be taken into account when dermatologists are considering toxic metals as a potential cause of alopecia areata in humans.
