In 36 patients (5.2%), the UDS contributed to establishing the diagnosis. Tetrahydrocannabinol (THC) was the most common substance identified in these cases. Hospitalization was more common in the UDS-established diagnosis group (33\/36, 91.7% vs. 494\/657, 75.2%;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.026), and involvement in child protective services was also more common (26\/36, 72.2% vs. 53\/657, 8.1%;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001).
