"I have to pick my battles": a mixed-methods study exploring food insecurity and dietary restrictions in pediatric kidney disease.
Article in Pediatric nephrology (Berlin, Germany), 2025. 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
backgroundFood insecurity (FI) is prevalent among children with chronic kidney disease (CKD), but its impact on health outcomes, and feasibility of prescribed diet restrictions is unknown. Accordingly, this study aims to explore associations of FI and CKD outcomes, and understand its role in following prescribed kidney diet recommendations.
methodsWe performed a mixed-methods single-center cohort study of children with advanced CKD or kidney failure. Demographics, socioeconomic status, and health outcomes were compared across FI status; associations between FI and CKD outcomes were explored using multivariable regression. A qualitative sub-analysis of de-identified caregiver interview transcripts was analyzed for themes around diet restrictions.
resultsThere was a trend that FI patients were more likely to be of Black race (33% vs. 20%); have public insurance (67% vs. 48%); need more blood pressure medications (2 [0.75,3] vs. 1 [0,3]); and have a higher likelihood of emergency department (42% vs. 25%) or intensive care unit encounters (25% vs. 14%). There were no associations of FI and outcomes of interest. Major themes that emerged from caregiver interviews include (1) understanding of the kidney diet focuses on foods to avoid; (2) adapting to suggested dietary restrictions requires changes in meal preparation; and (3) challenges to adherence include social stigma, growth, budget, and time.
conclusionsThe impact of FI on children's medical needs with CKD remains inconclusive but trends suggest a higher risk. Regardless of FI status, adhering to prescribed diet restrictions in kidney disease involves significant dedication. Challenges involve food availability, a child's response to restrictions, and social stigma.
