In a nested case–control analysis, adjusted odds ratios (ORs) for cancer overall were 1.50 (95% CI 1.30–1.74) for psoriasis of ≥4 years duration and 1.53 (95% CI 0.97–2.43) for patients receiving systemic treatment (marker of disease severity). Lymphohematopoietic malignancy risk was ...
In the case-control analysis based on definite cases and their controls, the unadjusted matched odds ratio (95% confidence interval) for current versus past use of inhibitors was 5.16 (2.21-12.05). The estimate was similar when all cases (definite and probable) and their corresponding controls ...
这一设计方案于1973年由美国流行病学家Mantel最早提出,称其为综合性病例对照研究(synthetic case control study),1982年正式提出巢式病例对照研究(nested case-control study),这是将队列研究与病例对照研究相结合的一种研究方法。 它在国际流行病学协会出版的《流行病学词典》(John M.Last主编,1988)中的定义为:...

For many research questions, the nested case-control design potentially offers impressive reductions in costs and efforts of data collection and analysis compared with the full cohort approach, with relatively minor loss in statistical efficiency . The nested case-control design is particularly ...
In binary analysis of the QoL (with a cutpoint of 2), low parental education, having a sibling, dental visit history for complaints and irregular/no toothbrushing were detected as significant predictors of poor QoL (p value <0.001). The RR of negative impact on QoL was fourfold (95% CI...
