The frequency of coughing pigs, e.g., the number of coughing pigs divided by total number of pigs in pen given a DPI, as measured by the observer was a significant predictor for MHP DNA detection in pen oral fluid samples (beta coefficient = 4.85; SE = 1.59; P < 0.001; Model A) and nearly significant in pen drinker wipes (beta coefficient = 3.25; SE = 1.88; P = 0.08; Model B).
