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

contextThe timing of a woman's final menstrual period (FMP) in relation to her age is considered a valuable indicator of overall health, being associated with cardiovascular, bone health, reproductive, and general mortality outcomes.

objectiveThis work aimed to evaluate the relationship between hormones and the "time to FMP" when daily hormone trajectories are characterized by their 1) entropy, and 2) deviation from premenopausal/stable cycle patterns (representing a textbook "gold standard"; GS).

methodsAs part of the Study of Women's Health Across the Nation, urinary luteinizing hormone (LH), follicle-stimulating hormone (FSH), estrogen conjugates (E1C), and pregnanediol glucuronide (PDG) were measured daily from a multiracial sample of 549 mid-life women for the duration of one menstrual cycle. Hormone trajectories were mapped onto a plane with axes representing Fuzzy entropy (FuzzEn) and the normalized dynamic time warping distance (DTW) from the GS.

resultsViewing FSH, E1C, PDG, and LH through this lens reveals that, contrary to existing wisdom, PDG stands out as a powerful predictor/descriptor of "time to FMP." Using cluster analyses to discretize PDG on the DTW/FuzzEn plane yields statistically different survival curves, and Cox proportional hazards analyses confirm that this separation persists in the presence of known covariates of FSH, antimüllerian hormone, age, body mass index, financial hardship, smoking status, and cycle length.

conclusionSince PDG is generally not considered a predictor/descriptor of ovarian aging, this work validates the DTW/FuzzEn analytical framework and introduces another metric/hormone to be used in FMP-related preventive care.
