Diet and physical activity behaviors among women with polycystic ovary syndrome (PCOS): Are they different from healthy women?

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
objectiveTo investigate the diet and physical activity habits among women with polycystic ovary syndrome (PCOS) and compare them with age and BMI matched controls.
methodsThis cross-sectional cohort study included 90 women with PCOS from a diverse population representing various socioeconomic backgrounds in both urban and rural areas. Ninety women with PCOS, diagnosed according to Rotterdam criteria, were matched for age and BMI with 270 healthy women from the same community who served as a reference group. Both groups completed interviews about their dietary habits and physical activity using a validated 126-item Food Frequency Questionnaire (FFQ) and Exercise questionnaire. Additionally, dietary assessment was performed using Diet-Cal Software.
resultsBased on 24-hour dietary intake calculations, total calorie, carbohydrate, and fat consumption were higher, while fiber intake was lower in the PCOS group. When assessing and comparing the frequency of specific food groups using a food frequency questionnaire, certain foods-such as milk/milk products, processed foods, cereals, root/tubers, pulses, and nuts-were found to be more commonly consumed. Physical activity hours were significantly lower in the PCOS group. Univariate, multivariate, and explainable machine learning models were also developed to explore the relationship between dietary habits and physical activity in women with PCOS.
conclusionsThe PCOS group differs from the control group in overall calorie, carbohydrate, fat, and fiber intake. The PCOS group also exhibited poorer physical activity behaviors compared to the control group.
