Each of the 13 Yale-Brown symptom categories is located in the first column and row of the matrix. Raw factor loading co-occurrences are displayed above the diagonal. Symptom categories which load highest on the same factor in at least half of studies are highlighted in bold. The sample size weighted similarity coefficient is displayed below the diagonal. Similarity coefficients greater than 0.4 are highlighted in bold.
