Standard scores were used to calculate the correlation coefficient. Significance was determined based on a p-value threshold of 0.05. Slope corresponds to a regression line fitted using immunoassay score as independent variable and SOMA score as dependent variable. Samples from all available cohorts were used for correlation calculation.
