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

Introduction: The aim of this systematic review was to evaluate the current evidence regarding resting metabolic rate fluctuations across menstrual cycle phases in healthy, naturally menstruating females. Methods: A systematic search was conducted in the PubMed and Web of Science databases for articles published from January 2020 to September 2025. Of the 331 records identified, seven studies met the eligibility criteria and were included. Results: Five studies reported a trend toward an elevated metabolic rate during the luteal phase, with four reporting statistically significant increases. The estimated increase ranged from approximately 30 to 120 kcal/day. Conclusion: However, the magnitude of this physiological shift appears to be small (approximately 3-5%) and may overlap with typical day-to-day biological variability, methodological limitations, or measurement error, potentially contributing to inconsistent findings across studies. Future research should prioritise longitudinal, repeated-measures designs with confirmed ovulation to accurately quantify menstrual cycle-related metabolic fluctuations.
