However, it is the diagnostic gold standard for central precocious puberty (CPP), which in girls is defined as the onset of secondary sexual characteristics before the age of 8\u00a0years accompanied by breast buds, accelerated growth, and advanced bone age. This meta-analysis was performed to compare the diagnostic value of urinary gonadotropins and the GnRH stimulation test for CPP.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We searched six databases for relevant literature.

The meta-analysis of the ULH to urinary follicle-stimulating hormone (UFSH) ratio revealed an AUC of 0.8116 (sensitivity\u2009=\u20090.79, specificity\u2009=\u20090.84).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Both the ULH level and ULH:UFSH ratio are effective and available approaches for CPP diagnosis.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Trial Registration<\/jats:title>\n                <jats:p><jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/doi.org\/10.37766\/inplasy2021.12.0076\">INPLASY\u00a02021120076<\/jats:ext-link>.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12887-022-03481-1","type":"journal-article","created":{"date-parts":[[2022,7,28]],"date-time":"2022-07-28T11:03:46Z","timestamp":1659006226000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The value of urinary gonadotropins in the diagnosis of central precocious puberty: a meta-analysis"],"prefix":"10.1186","volume":"22","author":[{"given":"Dan","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueying","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junfei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xi","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,7,28]]},"reference":[{"issue":"4","key":"3481_CR1","doi-asserted-by":"publisher","first-page":"313","DOI":"10.1016\/j.pedneo.2016.04.004","volume":"58","author":"CT Lee","year":"2017","unstructured":"Lee CT, Tsai MC, Lin CY, Strong C.
