The association between plant protein intake and cancer risk: a prospective cohort study.

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
backgroundTo examine the association between plant protein intake and the risk of overall and site-specific cancers in a large prospective cohort.
methodsThis prospective cohort study included 192,428 participants from the UK Biobank, recruited from 2006 and followed until 2023. Plant protein consumption information was assessed using validated 24-hour dietary recalls. Hazard ratios (HRs) and 95% confidence intervals (CIs) for the association of plant protein consumption with cancer risk were calculated using Cox proportional risk regression models. Nonlinear associations were tested using restricted cubic spline analysis.
resultsDuring a median follow-up of 11.2 years, 22,779 cancer events were recorded. Compared to participants in the lowest quartile of plant protein intake, those in the highest quartile had HRs for overall cancer, lung cancer, renal cancer, and colorectal cancer of 0.91 (95% CI = 0.88-0.95, P < 0.001), 0.86 (95% CI = 0.73-1.00, P = 0.048), 0.69 (95% CI = 0.55-0.87, P = 0.002), and 0.89 (95% CI = 0.79-1.00, P = 0.046), respectively. Furthermore, each 10% increase in the ratio of plant protein to total daily protein was associated with a 3% lower overall cancer risk (HR = 0.97, 95% CI = 0.95-0.98, P < 0.001). Subgroup analyses suggested that the negative association was more pronounced in male. Among individuals who did not meet the WHO-recommended protein intake, a nonlinear association between plant protein intake and overall cancer risk was observed, characterized by a modest reduction in risk at moderate intake levels with no further risk reduction at higher intake levels (P for nonlinearity = 0.02).
conclusionThis cohort study indicates that higher dietary plant protein intake is significantly associated with a reduced risk of overall and specific cancers, including lung, renal, and colorectal cancer. These findings support the notion that increasing the consumption of plant protein-rich foods is beneficial for health.
