All Log10 C. difficile DNA concentrations reported in the manuscript are incorrectly low by a factor of 10 and, thus, represent the number of C. difficile DNA copies/100uL feces, not DNA copies/mL, as labeled. This includes the Y-axis labels for Figure 1 and the 95 % sensitivity cutoff for prediction of toxin status. The appropriate quantitative cutoff to detect 95 % of toxin positive samples is ≥5.1 Log10 C. difficile tcdB DNA copies/mL. All other proportions, relationships and conclusions remain accurate and valid. The authors regret any confusion this error may cause.
