Hyperandrogenism increases late spontaneous miscarriage in polycystic ovary syndrome women due to cervical insufficiency? A propensity-score matching study.
Article in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe potential effects of hyperandrogenism (HA) on pregnancy outcomes among polycystic ovary syndrome (PCOS) patients are still unknown. The aim of this study was to explore the impact of HA on miscarriage rate after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment in PCOS patients.
methodsWomen diagnosed with PCOS who underwent the first autologous IVF/ICSI cycles using gonadotropin-releasing hormone agonist (GnRH-a) protocols for ovarian stimulation during the period from January 2016 to December 2022 were included. Women were divided into the HA and non-HA group according to Hyperandrogenemia (serum testosterone level > 0.48 ng/mL), and/or the presence of hirsutism. Pregnancy outcomes were compared before and after propensity-score matching (PSM). Multiple logistic regression models were performed to demonstrate the independent impact of HA on pregnancy outcomes.
resultsA total of 3066 patients were included. PCOS women with HA experienced a notably higher rates of late spontaneous miscarriage (LSM) as compared to those without HA before and after PSM (8.8% versus 3.5%, P < 0.001; 8.9% versus 3.9%, P = 0.001, respectively), but comparable rates of clinical pregnancy, early spontaneous miscarriage, and live birth. After adjusting for possible confounding factors, the logistic regression confirmed that HA was independently associated with the increased risk of LSM (adjusted OR: 2.540, 95% confidence interval: 1.326-4.672, P = 0.003). For the specific reasons for LSM, cervical insufficiency accounted for a larger proportion in women with HA than their counterparts without HA (15/32 versus 7/33, P = 0.029).
conclusionsAndrogen excess is postulated to play a role in late miscarriage via increased likelihood of cervical insufficiency.
