borderline non-significantP = 0.06
The correlation between the quadratic term CEB 2 and lifespan was large, negative and significant in three of four models (no covariates: r G = −1.09, P = 0.003, only mother identifier as random effect: r G = −1.73, P = 0.04, only education as random effect: r G = −0.85, P = 0.01), and borderline non-significant in the model with only the father identifier ( r G = −1.61, P = 0.06).
