1 · What the graph read from it

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.

2 · The registry

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

Objective: To study utero-placental vascular development from the first trimester onward in pregnant women with polycystic ovary syndrome (PCOS) and successful live births, compared with pregnant women without PCOS, after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment or natural conception. Design: Prospective periconceptional cohort study in a single tertiary hospital. Subjects: Participants with ongoing pregnancies with available serial three-dimensional ultrasound scans were divided into 3 groups: women with PCOS; subfertile group, pregnancies who conceived via IVF/ICSI without PCOS; and fertile group, pregnancies who conceived naturally without PCOS. Exposure: PCOS diagnosis. Main Outcome Measures: During the first-trimester, placental volume (PV) and utero-placental vascular volume (uPVV) were measured offline in three-dimensional ultrasound volumes obtained at 7, 9, and 11 weeks' gestational age (GA) using Virtual Organ Analysis and Virtual Reality. Serial measurements were obtained from uterine artery pulsatility and resistance indices (UtA PI and UtA RI) measured by pulsed-wave Doppler ultrasound as well as mean arterial pressure at 7, 9, 11, 13, 22, and 32 weeks' GA. Similarly, the umbilical artery PI and RI were measured at 22 and 32 weeks' GA. Results: We included 206 pregnancies in our study (PCOS n = 41; subfertile n = 63; fertile n = 102). Significantly negative associations were observed between PCOS and placental measurements (PV, uPVV, and their ratio) at 11 weeks' GA with both the subfertile and fertile group as reference (e.g., uPVV 11 weeks' GA: beta Conclusion: Women with PCOS show decreased first-trimester placental development at 11 weeks' GA compared with pregnancies without PCOS in the subfertile and fertile group. Additionally, these women also display lower UtA PI and UtA RI compared with women without PCOS. These results support the hypothesis that PCOS impacts early placental development, potentially contributing to adverse pregnancy outcomes. Further research should focus on the underlying pathophysiology and the modifying role of IVF/ICSI treatment.
