Odds Ratios and 95% confidence intervals representing the odds of a stroke diagnosis per 1 unit increase in log transformed urinary tungsten (expressed as µg per mg of urinary creatinine) for NHANES participants less than 75 years of age or less than 50 years of age.

aThe adjusted models include age, sex, ethnicity, SES, smoking, occupation, BMI, hypertenstion, hypercholesterolemia, molybdenum and cobalt concentration as covariates.
bIn this model all urinary tungsten measures were included, including the 503 individuals with a concentration below the lowest detectable limit.
Statistical significance is denoted by ?, * and ** representing P<0.1, P<0.05 and P<0.01 respectively.
