Summary of P values from tests of association with NHL for all analytes included in the analysis (N = 67).P values for analytes detectable in less than 50% of samples (marked by an asterisk), computed using Wald statistic of regression model parameters for dichotomized analyte level (< lower limit of detection vs detectable). P values for all other analytes were computed using Wald statistic of regression model parameters for analyte intracategory medians modeled as a continuous variable.
