Results of the linear regression analyses of age, BMI and alcohol consumption on liver function test proteins.

Abbreviations: N = number of individuals, F = F test statistic, Chi2 = chi-square test, p = level of significance, R2 = Adjusted R2 explaining the proportion of the total variance explained.¶We report F-test statistics with 2 degrees of freedom from all regression analyses taking into account the relatedness between the twin pairs.†For alcohol consumption truncated Gaussian regression was used due to the half normal distribution of the alcohol data.
