Changes in hormones and experimental pain sensitivity in healthy girls: an exploratory longitudinal pilot study.
Article in Pain reports, 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
Introduction: Adolescence is a period of drastic biopsychosocial change that affects the trajectory of health into adulthood. Cross-sectional studies have reported that older youth typically exhibit lower experimental pain sensitivity than younger youth, but only one study thus far has directly examined this longitudinally. The factors contributing to changes in pain sensitivity remain unclear, but sex hormones, which dramatically fluctuate during adolescence, could play a key role. Objectives: This longitudinal study aimed to examine changes in experimental pain sensitivity/modulation and their relationship to changes in sex hormone levels. Methods: Healthy girls (n = 35, 9-16 years old) completed quantitative sensory testing (QST) at baseline and 1-year follow-up including thermal/pressure pain threshold; heat/cold pain intensity; cold pain tolerance; mechanical temporal summation; offset analgesia; and heat/pressure conditioned pain modulation. Serum blood samples were analyzed for total testosterone, dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), DHEA-sulfate (DHEA-S), and androstenedione (A4). Pain measures that significantly differed from baseline to follow-up were dependent variables in bootstrapped linear regression models with sex hormones as individual predictors in separate models. Additional regressions included baseline age and changes in pubertal stage and menstrual phase as covariates. Results: Cold pain threshold (CPT) increased over 1 year (baseline = 11.93°C, follow-up = 15.72°C, Conclusion: These findings suggest that during puberty, changes in sex hormone levels may have minor contributions to changes in experimental pain sensitivity in healthy girls.
