Saffron and Sleep Quality: A Systematic Review of Randomized Controlled Trials.
Review in Nutrition and metabolic insights, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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: Sleep quality is defined as an individual's consent to sleep experience. Poor sleep quality has important adverse health outcomes. There are drugs to treat sleep disorders but consumption of these drugs is accompanied by adverse effects whereas herbal treatments have fewer side effects. Saffron is spice obtained from Crocus sativus flower. Several articles have been done on its effects on the quality of sleep and its safety. This review for the first time critically evaluates effect of saffron on sleep quality improvement. Method: The search technique aims to get all related published data-based up to 2022 articles. PubMed, Central, Google Scholar, and Scopus were examined. Only full reports were evaluated (abstracts were excluded). The first screening was done by title and abstract. Then full text of articles was read and irrelevant articles were removed. Duplicate articles were also removed by Endnote. By using Cochrane risk of bias tool assessment, a quality score based on probability of bias was given. Methodological characteristics were also evaluated using the criteria of Stevinson and Ernst. Result: In the systematic review, 5 randomized clinical trials with 379 participants from 3 countries were identified. In placebo-comparison trials, saffron contains a large treatment. Conclusion: It seems that saffron has a beneficial influence on duration and quality of sleep. Saffron, crocin, and safranal induce hypnotic effects by increasing the duration of sleep. Research conducted so far provides initial support and safety for use of saffron to improve sleep quality.
