To estimate the rate of underreporting of AIDS (acquired immune deficiency syndrome) to the Federal Centre for AIDS (FCA), in 1988 the initials, date of birth and place of residence of 66 patients with AIDS known to the Toronto Sexual Contact Study (TSCS), 65 patients with AIDS known to the Vancouver Lymphadenopathy-AIDS Study (VLAS) and other participants in both studies who did not have AIDS were sent to the Bureau of Epidemiology and Surveillance, FCA. The FCA conducted a manual record linkage to link these data to the national registry of reported cases. The rate of underreporting was 12% (8/65) for the VLAS and 18% (12/66) for the TSCS. The specific diagnosis was not related to the rate of underreporting. For the TSCS the rate of underreporting had increased from 0% in 1983-84 to 44% in 1987-88 (p = 0.001). Differences in the observed rates of underreporting between the two studies are likely the result of differences in the reporting responsibilities of physicians involved in the studies.
为估算向联邦艾滋病中心（FCA）上报艾滋病（获得性免疫缺陷综合征）的漏报率，1988年，多伦多性接触研究（TSCS）所知晓的66例艾滋病患者、温哥华淋巴结病 - 艾滋病研究（VLAS）所知晓的65例艾滋病患者以及两项研究中其他未患艾滋病的参与者的姓名首字母、出生日期和居住地址被发送至FCA的流行病学与监测局。FCA进行了人工记录匹配，以将这些数据与上报病例的国家登记册相链接。VLAS的漏报率为12%（8/65），TSCS的漏报率为18%（12/66）。具体诊断与漏报率无关。对于TSCS，漏报率从1983 - 1984年的0%增至1987 - 1988年的44%（p = 0.001）。两项研究中观察到的漏报率差异可能是参与研究的医生报告职责不同所致。
