How Healthy Are the Diets of Cancer Survivors? Characteristics of Those Most at Risk and Opportunities for Improvement.
Article in Journal of the National Comprehensive Cancer Network : JNCCN, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundDiet quality and adherence to dietary guidelines are strong predictors of positive cancer outcomes among survivors.
methodsA cross-sectional analysis was conducted using 2-day dietary recalls from a nationwide sample of 818 survivors of 9 obesity-related cancers with ≥70% 5-year survival who expressed interest in a web-based diet and exercise trial. Total diet quality scores and component subscores were generated using the Health Eating Index-2020 (HEI-2020). Subgroup analyses examined differences by cancer diagnosis and treatment, body weight status, and sociodemographic factors.
resultsThe mean [SD] HEI-2020 score among survivors was 51.6 [12.05] out of 100-approximately 10 points below norms for comparably aged Americans in the general population. Clinically meaningful deficits were observed for intakes of fruits, vegetables, dairy products, and protein (especially from plant and seafood sources). Survivors' intakes also included excessive amounts of refined grains. Compared with the general population, however, survivors' intakes more closely aligned with guidelines in terms of higher whole grain intake and lower consumption of sodium, saturated fat, and sugar (including sugar-sweetened beverages). Overall diet quality and/or component scores were significantly lower among younger survivors (age <65 years) and those within 5 years of diagnosis, with obesity (body mass index ≥30 kg/m2), of lower education (high school diploma or less), and residing in areas of higher socioeconomic deprivation (Area Deprivation Index ≥50th percentile) (all P<.05). No significant subgroup differences were detected by cancer type or treatment.
conclusionsDiet quality among survivors of obesity-related cancers is notably suboptimal. Clinicians should leverage survivors' interest in diet and exercise interventions to provide support and referrals targeting identified areas of need, particularly for those at highest risk, such as individuals with obesity, within 5 years of diagnosis, aged <65 years, with a high school diploma or less, and residing in areas of higher socioeconomic deprivation.
