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: There is no clear-cut evidence in the existing medical literature of an association between iron deficiency and nonscarring alopecia. Objective: The objective of the study was to conduct a systematic review of the medical literature on the prevalence of iron deficiency in women with nonscarring alopecia and compare their ferritin levels with those of women without this condition. Methods: The electronic databases PubMed, Scopus, and Web of Science were searched between June 15, 2019, and July 24, 2019. Studies that evaluated the prevalence of iron deficiency in women with nonscarring alopecia and/or compared ferritin levels in women with and without this condition were entered into the meta-analysis. Thirty-six of 928 identified studies entered the systematic meta-analysis. The meta-analysis was performed using the random-effects method. Results: The overall number of participants was 10,029. The prevalence of ferritin levels from 10 to 15 ng/dL and below was 21% (12; 29). Women with nonscarring alopecia had lower ferritin values at MD = -18.51 ng/dL (-25.85; -11.16, Conclusion: Women with hair loss can benefit from higher ferritin levels.
