One dermatologist recorded the clinical signs of abnormal toenails. Nail specimens were collected from all abnormal nails, and the presence of tinea unguium was confirmed when fungus was detected by direct microscopy. Foot temperature was measured by infrared thermography. A receiver operating characteristic curve was used to assess the ability to determine whether residents with subungual hyperkeratosis have tinea unguium and to determine the cut\u2010off point.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among the people with subungual hyperkeratosis, the mean toe temperature in the tinea unguium\u2010positive group (30.2\u2009\u00b1\u20092.6\u00b0C) was significantly lower than that in the tinea unguium\u2010negative group (32.8\u2009\u00b1\u20093.2\u00b0C,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.001). The area under the receiver operating characteristic curve was 0.74 (95% confidence interval 0.621\u20130.876), and the threshold temperature was set at 33.0\u00b0C, resulting in a sensitivity of 81.8% and specificity of 65.7%.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      Our study suggests that foot temperature can be used to screen for tinea unguium in people with subungual hyperkeratosis.
