The role of genetic variation in apolipoprotein response to diet among Brazilians with cardiovascular disease.
Article in European journal of clinical nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01620398 (The Brazilian Cardioprotective Nutritional Program to Reduce Events and Risk Factors in Secondary Prevention for Cardiovascular Disease), which is not on this 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.

Abstract
BACKGROUND/
objectivesData on the interaction between dietary patterns, single nucleotide polymorphisms (SNPs), and cardiometabolic markers remain limited in genetically admixed populations, particularly among individuals with established cardiovascular disease (CVD). This study aimed to evaluate how SNPs modulate the effects of dietary interventions on apolipoprotein concentrations (A-I, A-II, B, C-II, C-III, and E) in Brazilians undergoing secondary cardiovascular prevention. SUBJECTS/
methodsThis sub-study used data from the three-year multicenter BALANCE Trial, which enrolled individuals aged ≥40 with established CVD. Participants were assigned to either an intervention group (following the Brazilian Cardioprotective Diet with intensive monitoring) or a control group receiving general dietary advice. Apolipoproteins were measured via multiplex immunoassay, and SNPs were genotyped using the Axiom 2.0 Assay. GWAS and adjusted linear regression models assessed associations and gene-diet interactions related to apolipoproteins.
resultsA total of 266 participants (118 in the intervention group and 148 in the control group) were analyzed. After three years, significant SNP-diet interactions affecting log-transformed apolipoprotein concentrations were identified at a genome-wide significance threshold of 10⁻⁵. For each apolipoprotein evaluated, the following polymorphisms were associated: Apo A-I (rs11542163_T, rs11759163_T, rs13396579_C), Apo A-II (rs11197283_T, rs13185245_G, rs7666435_C), Apo B (rs13205819_G, rs926561_C), Apo C-II (rs143862519_TTC, rs674845_A, rs931606_G), Apo C-III (rs2247572_T, rs4506508_C, rs931606_G), and Apo E (rs4862401_G, rs6835179_G). Per-allele differences ranged from -0.65 mg/dL (Apo C-II, rs143862519_TTC) to +0.52 mg/dL (Apo B, rs13205819_G).
conclusionsOur findings show that genetic variants influence apolipoprotein responses to diet in Brazilians under secondary CVD prevention, supporting genotype-guided nutrition. CLINICAL TRIAL REGISTRY NUMBER: NCT01620398.
