Outcome variables were changes in plasma lipids, BMI, insulin resistance and plasma glucose. We searched MEDLINE and EMBASE for randomized trials and estimated the pooled within-group change in each outcome variable using a random-effects model. We performed subgroup analyses by study duration (&lt;12 months vs \u226512 months) and polycystic ovary syndrome (PCOS) status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Eighty-two clinical trials fulfilled the inclusion criteria. All progestins (except dienogest) increased plasma TG, ranging from 12.1 mg\/dL for levonorgestrel (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001) to 35.1 mg\/dL for chlormadinone (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001). Most progestins also increased HDLc, with the largest effect observed for chlormadinone (+9.6 mg\/dL,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001) and drospirenone (+7.4 mg\/dL,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001). Meanwhile, levonorgestrel decreased HDLc by 4.4 mg\/dL (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001).

Cyproterone slightly reduced plasma glucose. None of the progestins affected BMI or HOMA-IR. Similar results were observed in subgroups defined by PCOS or study duration.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Most progestins increase both TG and HDLc, their effect on LDLc varies widely.
