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: The number of supplements for nail health is continuously increasing, and consumers are no longer familial with them, which can create confusion, as they do not always understand what they are consuming, and some will seek advice from their dermatologist, who must have as clear and a precise answer. Summary: Biotin, collagen peptides, solubilized keratin MSM, and choline-stabilized orthosilicic acid have been shown to improve the clinical appearance of nails, strength, and brittleness. There is a lack of regulation from the health authorities concerning dietary supplements. Manufacturers are not required to carry out efficacy and safety studies before marketing. Key Messages: Dermatologists must be aware of the ingredients available on the market, their possible benefits but also their risks. It is important to specify to patients that our recommendations are as solid as the available evidence. In this article, we will discuss about the supplements available for nails, their mechanisms of action, and possible side effects.
