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

'Black stain' is a form of extrinsic staining affecting the buccal and palatal surfaces of primary and permanent teeth. It presents as an incomplete line of dark dots formed at the cervical third of the tooth, typically following the gingival margin and not extending to the proximal areas. There is no consensus on its prevalence, though it appears to vary between 2-20%, with an equal male and female distribution. Although the aetiology is not completely understood, its microflora is dominated by chromogenic bacteria, such as actinomyces and prevotella melaninogenica, and there appears to be a low incidence of caries in the presence of the stain. The cause of the dark pigmentation seems to be from iron deposits such as ferric sulphate, present due to a reaction with the products of bacterial metabolism. This paper aims to provide information on the diagnosis, aetiology and treatment considerations for black stain. A patient case report is also explored.
