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

A decrease in the ceramide content of the stratum corneum is known to cause dry and barrier-disrupted skin. In this literature review, the clinical usefulness of preparations containing natural or synthetic ceramides for water retention and barrier functions was evaluated. The PubMed, Cochrane Library, and Igaku Chuo Zasshi databases were searched using keywords such as "ceramide", "skincare products", "barrier + hydration + moisture + skin", and "randomized trial". All database searches were conducted in February 2019. Forty-one reports were selected based on the following criterion: comparative control studies that evaluated the effects of ceramide-containing formulations based on statistical evidence. Among the 41 reports, 12 were selected using the patient, intervention, comparison, and outcome approach. These 12 reports showed that external ceramide-containing preparations can improve dry skin and barrier function in patients with atopic dermatitis. However, a double-blinded comparative study with a large sample size is warranted for appropriate clinical use.
