Adjusted means and odds ratios for gastric precancerous lesions in relation to bacterial DNA levels, n = 119.

1Means of absolute bacterial counts (ng/µl) adjusted for age and sex. 2ORs estimated in relation to a standard deviation increase in the log-transformed bacterial DNA levels. Model 1 was adjusted for age and sex. Model 2 was further adjusted for race, smoking status, educational attainment, BMI, and H. pylori status. 3Bacterial counts in 1×102 ng/µl. 4Bacterial counts in 1×104 ng/µl. 5Cumulative burden is the sum of the log-transformed and standardized values of bacterial counts. 6Bacterial counts in 1×103 ng/µl.
