Abstract

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder associated with cardiovascular disease (CVD) risk factors and metabolic disturbances. This systematic review and meta-analysis was conducted to determine whether carotid intima-media thickness (CIMT), a marker of subclinical atherosclerosis, is higher in women with PCOS compared with women without PCOS. METHODS: Primary articles reporting the mean CIMT in women with PCOS and controls were identified using Ovid MEDLINE, EMBASE and PUBMED. We performed a random-effects meta-analysis and created forest plots of the mean difference in CIMT and conducted tests for heterogeneity and publication bias. Studies were grouped by quality, defined by reporting reproducibility of CIMT and averaging both common carotid arteries versus one side for CIMT. RESULTS: From the 36 eligible full-text studies, 8 studies were included in the systematic review and 19 studies were included in the meta-analysis (total n= 1123 women with PCOS, n= 923 controls). The summary mean difference in CIMT among women with PCOS compared with controls was 0.072 mm [95% confidence interval (CI) 0.040, 0.105, P < 0.0001] for highest quality studies, 0.084 mm (95% CI 0.042, 0.126, P = 0.0001) for good quality studies, 0.041 (95% CI -0.038, 0.120, P = 0.310) for fair-quality studies and 0.045 (95% CI -0.020, 0.111, P = 0.173) for lower quality studies. CONCLUSIONS: Larger studies with a well-defined PCOS population using rigorous methodology may be required to draw a more robust conclusion. However, these results suggest women with PCOS are at a greater risk of premature atherosclerosis, which emphasizes the importance of screening and monitoring CVD risk factors in women with PCOS.

  • Young women and adolescents with PCOS have early atherosclerotic cardiovascular disease, including increased carotid intimal medial thickness and carotid plaque.

    “Young women and adolescents with PCOS have been shown to have early atherosclerotic CVD, including increased carotid intimal medial thickness and carotid plaque.86, 87, 88, 89”

    From Increased Prevalence of Adverse Health Outcomes Across the Lifespan in Those Affected by Polycystic Ovary Syndrome: A Canadian Population Cohort (2024) · cites this paper as [86]

    The Conclusions report higher carotid intima-media thickness (CIMT) in women with PCOS than in controls, and note that most studies involved young women. The paper does not establish the claim for adolescents or report increased carotid plaque. It describes CIMT as subclinical atherosclerosis and cautions that CVD risk may not become evident until later in life. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
