Heterogeneity in Lipoprotein(a) Profile Changes Across the Menopausal Transition.
Article in medRxiv : the preprint server for health sciences, 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: Menopause may coincide with rising Lp(a) levels, a causal risk factor for atherosclerotic cardiovascular disease (ASCVD). Characterizing changes in Lp(a) across menopause may inform risk stratification and testing recommendations. . Methods: We examined changes in serum Lp(a) levels by menopausal status among women with Lp(a) measured at visits 1 and 2 in the UK Biobank. Lp(a) analyses were examined by menopausal status: those who underwent menopause (N=415), those who remained premenopausal (N=532), and those who remained postmenopausal (N=3,615) between visits. We examined the change in Lp(a) between visits stratified by visit 1 Lp(a) levels. The primary outcome was incident Lp(a) ≥125 nmol/L at visit 2, estimated using Poisson regression with adjustment for baseline age. Results: Data were available for 4,562 women (mean age at visit 1 = 57±7 years; median Lp(a) at visit 1 = 22 (IQR: 47) nmol/L; median time between visits = 4 (IQR: 1) years). At visit 1, median Lp(a) was slightly higher in postmenopausal women (23 nmol/L) than premenopausal women (19 nmol/L). Overall, median changes in Lp(a) between visits 1 and 2 were modest. Among women with intermediate visit 1 Lp(a) levels (75-125 nmol/L), those who transitioned through menopause experienced a median increase of 34.9 (-6.7, 53.0) nmol/L between visits, an approximately fourfold greater increase than for women who remained pre- (7.9 nmol/L) or postmenopausal (8.0 nmol/L). Further, 56% of women with intermediate visit 1 Lp(a) levels who transitioned through menopause between visits had incident Lp(a) ≥125 nmol/L at visit 2, compared with 29% and 28% of women who remained pre- or postmenopausal, representing an age-adjusted risk ratio of 2.26 (95% CI: 1.31, 3.90). Conclusion: Relying on a single lifetime Lp(a) measurement may miss clinically relevant increases during menopause. Repeat testing in women as they age may improve identification of those at high risk for ASCVD.
