Dietary protein intake in relation to metabolic syndrome reversion: findings from the Tehran lipid and glucose study.
Article in Scientific reports, 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
Dietary protein quantity and quality may influence metabolic regulation and cardio-metabolic outcomes, yet little is known about their role in metabolic syndrome (MetS) reversion, a beneficial transition linked to reduced disease risk. This study examined associations between total and source-specific dietary protein intake and MetS reversion in Iranian adults. Adults with MetS at baseline (Phase 3, 2006-2008) of the Tehran Lipid and Glucose Study were followed until Phase 6. Dietary intake was assessed using a validated 168-item food frequency questionnaire. Total, animal and plant-based protein, as well as protein food-specific sources (red meat, processed meat, poultry, dairy, legumes, and nuts) was categorized into tertiles. MetS reversion was defined as the transition from MetS to non-MetS during follow-up, categorized by timing: final phase, any phase, early, and sustained reversion. Cox proportional hazards regression models estimated hazard ratios (HRs) and 95% confidence intervals (CIs), adjusted for covariates. In the fully adjusted models, participants in the second tertile of animal protein intake had a significant lower HR for "any phase MetS reversion" (HR: 0.68; 95% CI: 0.48-0.96), compared to the participants in the first tertile. Also, participants in the second tertile of poultry intake had higher HRs for "any phase MetS reversion" (HR: 1.47; 95% CI: 1.03-2.09) and "early phase MetS reversion" (HR: 1.58; 95% CI: 1.01-2.46), compared to the participants in the first tertile. Furthermore, higher intakes of dairy products and nuts were associated with 48% (HR: 0.52; 95% CI: 0.31-0.86) and 43% (HR: 0.57; 95% CI: 0.35-0.92) lower HRs for "early phase MetS reversion", respectively. No significant associations were observed between dietary protein sources and sustained MetS reversion; however, the small number of sustained reversion events (n = 31, 5.4%) limited statistical power for this outcome, precluding definitive conclusions about long-term metabolic maintenance.
