nitrates has been researched along with Sensitivity and Specificity in 238 studies
Nitrates: Inorganic or organic salts and esters of nitric acid. These compounds contain the NO3- radical.
Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)
