Probabilistic Quantification Of Bias to Combine the Strengths Of Population-Based Register Data and Clinical Cohorts - Studying Mortality in Osteoarthritis
We propose to combine population-based register data, with a nested clinical cohort to correct misclassification and unmeasured confounding through probabilistic quantification of bias. We illustrate this approach by estimating the association between knee osteoarthritis and mortality. We used the Swedish Population Register to include all persons resident in the Skåne region in 2008 and assessed
