Effects of apolipoprotein E and solute carrier organic anion transporter family member 1B1 gene polymorphisms on statin efficacy and safety in dyslipidemic patients.
Article in Pharmacogenetics and genomics, 2026. 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
objectiveTo investigate the distribution of the apolipoprotein E ( ApoE ) and solute carrier organic anion transporter family member 1B1 ( SLCO1B1 ) polymorphisms in dyslipidemia patients and their impact on statin efficacy and safety.
methodsA retrospective analysis was conducted on dyslipidemic inpatients (April 2024-March 2025) who received statin therapy and genetic testing for SLCO1B1 (rs4149056) and ApoE (rs429358 and rs7412), to analyze the association of genotypes with lipid levels and safety indicators.
resultsThe final analysis included 238 hospitalized patients with dyslipidemia (156 males and 82 females) who met the inclusion criteria. The study population had a mean age of 60.61 ± 0.91 years (mean ± SEM). The allele frequencies for both ApoE and SLCO1B1 polymorphisms were in Hardy-Weinberg equilibrium ( P > 0.05). Analysis of statin efficacy revealed a significant association between ApoE genotype and atorvastatin response: E3 carriers demonstrated higher low-density lipoprotein cholesterol levels posttreatment compared to E2 carriers (2.85 ± 1.00 mmol/l vs. 2.28 ± 0.96 mmol/l, P = 0.026). However, no such association was found in patients administered rosuvastatin. For safety outcomes, comparisons of creatine kinase and alanine aminotransferase levels between carriers of the SLCO1B1 TC and TT genotypes showed no statistically significant differences.
conclusionAPOE polymorphisms influence statin efficacy. The E2 genotype is associated with better atorvastatin efficacy in lipid management. At low-to-moderate doses, the SLCO1B1 TC genotype did not increase safety risk, supporting its clinical safety.
