Effectiveness of myoinositol for polycystic ovary syndrome: a systematic review and meta-analysis

Zeng, Liuting, Yang, Kailin·2018·Endocrine

Abstract

Purpose To assess the effectiveness and safety of myoinositol for patients with PCOS.Methods In this meta-analysis, data from randomized controlled trials are obtained to assess the effects of myoinositol vs. placebo or western medicine in women with PCOS. The study's registration number is CRD42017064563. The primary outcomes included total testosterone, estradiol (E2) and the homeostatic model assessment (HOMA) of insulin resistance.Result Ten trials involving 573 patients were included. The meta-analysis results show that: compared with the control group, myoinositol may improve HOMA index (WMD -0.65; 95% CI -1.02, -0.28; P = 0. 0005) and increase the E2 level (WMD 16.16; 95% CI 2.01, 30.31; P = 0. 03); while there is no enough strong evidence that the myoinositol has an effect on the total testosterone level (WMD -16.11; 95% CI -46.08, 13.86; P = 0. 29).Conclusion Based on current evidence, myoinositol may be recommended for the treatment of PCOS with insulin resistance, as well as for improving symptoms caused by decreased estrogen in PCOS.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In the myo-inositol vs. metformin or estrogen subgroup, there is not enough strong evidence that myo-inositol improves hyperinsulinemia (WMD −0.99; 95% CI −2.43, 0.45; p = 0.19).

    “In the myo-inositol vs. placebo subgroup, myo-inositol is likely to improve hyperinsulinemia because of the lower fasting insulin (WMD −3.97; 95% CI −5.76, −2.18; p < 0.00001), while in the myo-inositol vs. metformin or estrogen subgroup, there is not enough strong evidence (WMD −0.99; 95% CI −2.43, 0.45; p = 0.19).”
  • In each subgroup, there is not enough strong evidence that myo-inositol has an effect on fasting glucose.

  • A systematic review and meta-analysis of randomized controlled trials showed that myo-inositol is likely to improve insulin resistance because of a lower HOMA index both in the myo-inositol vs. placebo comparison (WMD −1.11; 95% CI −1.39-0.83; p < 0.00001) and in the myo-inositol vs. metformin or estrogen comparison (WMD −0.33; 95% CI −0.60-0.05; p = 0.02).

    “Authors showed that myo-inositol is likely to improve IR because of the lower HOMA index both in the myo-inositol vs. placebo comparison (WMD −1.11; 95% CI −1.39–0.83; p < 0.00001) and in the myo-inositol vs. metformin or estrogen comparison (WMD −0.33; 95% CI −0.60–0.05; p = 0.02).”

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.
