The longitudinal association between artificial sweetener intake and the risk of type 2 diabetes among adults aged 18 years and older: a systematic review and meta-analysis.

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
Background: Artificial sweeteners are commonly used as sugar substitutes because they provide sweetness with little or no caloric content. However, the relationship between artificial sweetener consumption and type 2 diabetes (T2D) remains controversial. This meta-analysis was conducted to investigate the longitudinal association between artificial sweetener intake and T2D among adults. Methods: Electronic databases in English and Chinese were searched for prospective studies published from inception to March 2025. Using a random-effects model, the pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated to investigate the longitudinal association between artificial sweetener intake and T2D among adults aged 18 years and older. Between-study heterogeneity was assessed using the Results: A total of six cohort studies including 721,003 participants were analyzed in this meta-analysis. Compared with those with low or no consumption of artificial sweeteners, participants with higher artificial sweetener intake were more likely to develop T2D (pooled HR = 1.31, 95% CI = 1.16-1.49). Substantial heterogeneity was observed across studies ( Conclusion: A longitudinal association was observed between artificial sweetener intake and the risk of developing T2D among adults. This study has important public health implications. The findings of this study highlight that artificial sweeteners may not be a completely risk-free alternative to sugar in dietary interventions aimed at reducing high-energy sugar intake and suggest that their potential adverse metabolic effects should be considered in public health policy-making and clinical dietary recommendations regarding artificial sweetener intake.
