Identifying menstrual metrics as personal health markers: Age trends and individual footprints in temperature across 5674 cycles.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The menstrual cycle is a rich yet underused source of physiological information. To address this, we developed an open-source tool called WAVES (women's health assessment through variability in endocrine-related signals) that leverages physiological signals to extract menstrual cycle metrics and facilitate biomarker discovery. We tested it on basal body temperature data from 5674 nonconceptive cycles from 753 participants aged 18 to 42 years. We identified multiple associations between aging and menstrual metrics changes, including higher average temperatures, shorter cycles, and decrease in regularity across multiple metrics. In addition, values and cycle-to-cycle regularity of several metrics capturing temperature level and temporal structure of the cycle showed moderate to strong within-individual stability (ICC > 0.5). This work suggests that the WAVES algorithm can be used for advancing digital biomarker discovery and highlights the relevance of a personalized approach in the development of next-generation tools for women's health.
