Receiver operating characteristic curve (ROC) of the CNV parameters at Cz channel, comparing discriminative power of the independent variables, including late CNV (thick dark line), peak CNV (thick gray line) and CNV area (dashed line) for detecting participants with LBP versus healthy subjects. The reference line, diagonal of the square, represents the ability of the diagnostic test in differentiating LBP patients that is no better than chance level (null hypothesis)
