HIC and BPS were diagnosed by expert adjudication based on cystoscopic, clinical, and histopathological findings. GLR was calculated as serum gamma\u2010glutamyltransferase divided by peripheral lymphocyte count. Diagnostic performance was assessed using receiver operating characteristic analysis, and associations with HIC were evaluated using logistic regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 106 patients, 62 had HIC and 44 had BPS.
