Adverse effects of dyslipidemia on embryo quality and reproductive outcomes in specific subgroups undergoing first IVF/ICSI cycles: A case-control study.
Observational study in Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study aims to assess associations of dyslipidemia with in vitro fertilization/intracytoplasmic sperm injection outcomes in women undergoing their first ovarian stimulation and whether age, body mass index, or lipid levels modify these effects. This retrospective cohort study analyzed data from 327 dyslipidemic and 756 normal lipid women undergoing first in vitro fertilization/intracytoplasmic sperm injection cycle between April 2016 and March 2023. Primary outcomes included high-quality cleavage embryo rate, cumulative clinical pregnancy rate (CCPR), and cumulative live birth rate (CLBR). Generalized linear model and subgroup analysis adjusted for confounders. Overall, dyslipidemia showed no significant association with high-quality cleavage embryo rate, CCPR, or CLBR (all P > .05) but was associated with a lower oocyte retrieval rate (P = .025). Subgroup analysis showed that dyslipidemia was negatively associated with oocyte retrieval rate (adjusted odds ratio [aOR] [95% confidence interval [CI]]: 0.954 [0.911-0.999], P = .043) in women aged ≥35 years, with CCPR (aOR [95% CI]: 0.661 [0.459-0.953], P = .027) and CLBR (aOR [95% CI]: 0.667 [0.473-0.940], P = .021) in women aged <35 years, and cleavage rate (aOR [95% CI]: 0.901 [0.817-0.993], P = .036) in women with body mass index ≥28 kg/m2. Furthermore, marginally elevated triglyceride (TG) levels significantly reduced oocyte retrieval rate versus normal TG (aOR [95% CI]: 0.950 [0.912-0.988], P = .012). Dyslipidemia is associated with decreased CCPR and CLBR in young women, oocyte retrieval rate in elderly women, and cleavage rate in women with obesity. Marginally elevated TG levels associated with lower oocyte retrieval. Further large-scale prospective studies are warranted to validate these findings.
