Nomogram for Combining Probability with Diagnostic Likelihood Ratios

Note. A nomogram is a particularly helpful tool for quantifying the risk of bipolar disorder when certain warning signs are present (Youngstrom et al., 2009). Warning signs can include family history of bipolar disorder, a high score on a parent report questionnaire that is sensitive to manic symptoms, and/or a youth’s clinical presentation of decreased need for sleep, elevated, expansive mood, and grandiosity, or possible psychotic features.
