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

purposePolycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder among women of reproductive age with significant metabolic impairments. Time-restricted eating (TRE) has emerged as a promising dietary strategy for improving metabolic health. Although both early time-restricted eating (eTRE) and mid-day time-restricted eating (mTRE) have shown beneficial metabolic effects, their comparative efficacy in women with PCOS remains unclear. This study aimed to directly compare the effects of eTRE and mTRE on glycemic control, lipid profiles, and anthropometric outcomes in women with PCOS.

methodsIn this 6-week randomized controlled trial, 75 women with PCOS were allocated to one of three groups: eTRE (8:00 AM-6:00 PM), mTRE (11:00 AM-9:00 PM), or a control group with ad libitum eating. The primary outcome was fasting insulin level. Secondary outcomes included FBS, insulin resistance indices, lipid profile (total cholesterol (TC), LDL-C, HDL-C, and TG), body weight, BMI, waist circumference (WC), and dietary intake. Metabolic and anthropometric variables were assessed at baseline and post-intervention, while dietary intake was evaluated at baseline, mid-intervention, and study completion.

resultsBoth eTRE and mTRE significantly reduced FBS, fasting insulin, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), body weight, and WC compared with the control group (P < 0.05). Additionally, eTRE significantly improved TC (P < 0.001) and LDL-C levels (P = 0.01), whereas similar changes were not observed in the mTRE group.

conclusionTRE, particularly eTRE, appears to be an effective dietary intervention for women with PCOS, offering significant benefits for glycemic control, metabolic health, and weight management.
