In people with stable heart disease, older age is more strongly linked to higher PLIN2 protein levels than in people having a heart attack, suggesting age might affect PLIN2 differently in different types of heart disease.

Scientific Claim

The relationship between perilipin-2 (PLIN2) protein expression and age is stronger in chronic coronary syndrome (CCS) patients (r² = 0.24; p = 0.014) compared to ST-elevation myocardial infarction (STEMI) patients (r² = 0.09; p = 0.002), with a statistically significant difference between these correlations (p = 0.003).

Original Statement

PLIN2 expression was significantly correlated with age in STEMI (r2 = 0.09; p = 0.002) and CCS patients (r2 = 0.24; p = 0.014) (Figure 5). When performing a univariate analysis of variance, with variable PLIN2 of STEMI and CCS patients in relation to age, with linearly independent pairwise comparisons between the estimated marginal means, the difference in the two correlations was found to be significant (p = 0.003).

Assessment Explanation

The study is observational and reports different correlation strengths between groups. The claim appropriately uses 'stronger in' and 'statistically significant difference' which reflects the observational nature of the study.
