Abstract

BACKGROUND: Conflicting results regarding adiponectin levels in women with polycystic ovary syndrome (PCOS) have been reported. To evaluate adiponectin levels in PCOS, a systematic review of all studies comparing adiponectin levels in women with PCOS with healthy controls and a meta-analysis of those involving women with similar body mass index (BMI) were performed. The influence of possible effect modifiers, such as insulin resistance (IR) and testosterone, was investigated. The influence of obesity was investigated through a 'nested' meta-analysis after within-study BMI stratification and appropriate pooling. METHODS: Literature search was conducted through MEDLINE, EMBASE, Cochrane CENTRAL (through June 2008), references from relevant studies and personal contact with the authors. Thirty-one studies, reporting data on 3469 subjects, were reviewed and 16 included in the main meta-analysis. RESULTS: Women with PCOS demonstrated significantly lower adiponectin values [weighted mean difference (95% confidence interval) -1.71 (-2.82 to -0.6), P < 10(-4)], yet with significant between-study heterogeneity. Lower adiponectin levels are associated with the IR observed in women with PCOS, compared with controls. IR, but not total testosterone, was found significant among biological parameters explored in the meta-regression model. Hypoadiponectinaemia was present in both lean and obese women with PCOS when compared with non-PCOS counterparts. Data on high molecular weight (HMW) adiponectin are limited (three studies). CONCLUSIONS: After controlling for BMI-related effects, adiponectin levels seem to be lower in women with PCOS compared with non-PCOS controls. Low levels of adiponectin in PCOS are probably related to IR but not to testosterone. Total adiponectin should not be used as a biomarker of PCOS severity. Further investigation is needed for HMW adiponectin levels in PCOS.

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.
