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
Ultra-processed foods (UPF) are increasingly linked to negative health outcomes, including chronic diseases and mortality. Recent evidence suggests that UPF may accelerate biological ageing, potentially explaining their harmful effects. Therefore, this study was aimed to investigate associations between UPF intake categories and mortality risk, examining biological ageing's mediating and modifying effects. We used a prospective cohort design including 172,225 participants in the UK Biobank who completed 24-h dietary recall questionnaires. UPF were classified according to the NOVA system. Cox proportional hazards models were used to evaluated associations between UPF intake and both all-cause and cause-specific mortality. Biological ageing was assessed using PhenoAge acceleration, with the bootstrap method examined mediation effects and delta method assessed interaction between UPF intake and biological ageing on mortality risk. Participants consuming > 8 servings/day of total UPF showed higher mortality risk compared to those consuming ≤ 3.5 servings/day (HR = 1.15; 95% CI 1.07-1.23). Analyses by UPF subgroups revealed positive associations with mortality risk for plant-based UPF (HR = 1.02, 95% CI 1.01-1.03), artificial sweeteners (HR = 1.05, 95% CI 1.03-1.08), and beverages (HR = 1.04, 95% CI 1.03-1.05). Biological ageing mediated 14.4%, 27.5%, and 8.3% of these associations, respectively. A significant additive interaction was observed between high packaged food intake (> 1 servings/day) and accelerated biological ageing on mortality risk (RERI = 0.21, 95% CI 0.01-0.41), while breakfast cereals showed potential protective interactions. UPF consumption may increase mortality risk through biological ageing, with varying effects across subgroups. Strategic dietary modifications, reducing harmful UPF while potentially increasing protective ones, may help mitigate mortality risks.
