Note. CIHI false-negative cases are those identified in the TGLN registry (referent standard) but not by the algorithm. Frequencies are not reported because in accordance with ICES privacy policies, cell sizes ≤5 cannot be reported. CIHI = Canadian Institute for Health Information; TGLN = Trillium Gift of Life Network; ICES = Institute for Clinical Evaluative Sciences.
