Association of dietary phytochemical index with metabolic markers, serum asymmetric dimethylarginine and atherogenic indices in patients with polycystic ovary syndrome.
Article in Nutrition & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundPolycystic ovary syndrome (PCOS) is associated with an increased risk of cardiovascular diseases (CVD). Plant-based diets are associated with reduced CVD risk factors. This study aimed to explore the associations between dietary phytochemical index (DPI) and asymmetric dimethylarginine (ADMA), lipid profile, atherogenic indices, and other metabolic biomarkers in women with PCOS.
methodsIn this cross-sectional study, 150 females aged 18-45 years diagnosed with PCOS were recruited. An interviewer-administered questionnaire was applied to gather the relevant demographic characteristics, detailed clinical information, and lifestyle habits of participants. A validated semi-quantitative food frequency questionnaire was used to assess dietary intake, and DPI was calculated accordingly. We used multiple linear regression to determine the association between serum concentrations of ADMA, total testosterone, sex hormone-binding globulin (SHBG), fasting serum glucose (FSG), insulin, and lipid profile, as well as atherogenic indices across quartiles of DPI.
resultsThere was a negative correlation between the DPI and serum levels of ADMA (p-trend = 0.022), triglycerides (TG) (p-trend = 0.003), oxidized low-density lipoprotein cholesterol (ox-LDL) (p-trend = 0.001), insulin (p-trend = 0.045) and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) (p-trend = 0.018). Moreover, there was a tendency for visceral adiposity index (VAI) (p-trend = 0.005) and atherogenic index of plasma (AIP) (p-trend = 0.001) to decrease as the quartile categories of DPI increased. No significant regular trend was found for serum levels of FSG, SHBG, total testosterone, other lipid profiles, and lipid accumulation product (LAP).
conclusionsThese findings suggest that adherence to a phytochemical-rich diet decrease the CVD risk factors in PCOS patients.
