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

Time-restricted eating (TRE), a dietary strategy that aligns food intake with circadian rhythms, has emerged as a promising non-pharmacological approach for improving glycemic control in patients with type 2 diabetes. This systematic review and meta-analysis evaluated the effects of TRE on glycemic outcomes by analyzing eight randomized controlled trials involving 312 participants with type 2 diabetes or impaired fasting glucose. Meta-analyses of six eligible studies demonstrated that TRE significantly reduced fasting glucose (mean difference [MD]: -0.74 mmol/L; 95% CI: -1.13 to -0.36) and glycated hemoglobin (ΔHbA1c) (MD: -0.11%; 95% CI: -0.15 to -0.07) and increased time in range (TIR) for blood glucose (MD: +10.51%; 95% CI: 6.81 to 14.21). Improvements in fasting glucose and HbA1c were modest but consistent, while the increase in TIR showed no between-study heterogeneity, suggesting a robust and reproducible benefit of TRE on glycemic stability. These findings support the clinical feasibility and effectiveness of TRE as a dietary intervention in diabetes management. However, further high-quality trials with standardized protocols and longer follow-up are needed to confirm long-term efficacy and inform guidelines.
