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

The optimal frequency of water bathing/showering in atopic dermatitis (AD) is unknown. We sought to determine the efficacy of different bathing/showering frequencies at improving AD severity. A systematic review and meta-analysis was performed of studies evaluating the clinical efficacy of bathing/showering regimen in AD. MEDLINE, EMBASE, SCOPUS, LILACS, Cochrane, China National Knowledge Infrastructure, Taiwan electronic periodical services and CiNii were searched. Two authors independently performed title/abstract and full-text review and data extraction. All 13 included studies were prospective and demonstrated numerically reduced AD severity in patients treated with a water bathing/showering regimen in ≥ 1 time-point compared with baseline. In random-effects regression models, baths/showers ≥ 7 vs. < 7 times per week were not associated with significant differences of Cohen's D scores for eczema area and severity index (n = 5 studies; least-square means: 1.34 vs. 0.90; P = 0.45; I
