We consider the very fre...

Double-Robust Adjustment for Confounding and Missing Covariate Data in Cohort and Case-control Studies Modern epidemiologic studies often aim to evaluate the causal e陇ect of a point exposure on the risk of a disease from cohort or case-control observational data. Because confounding bias is of se...
Propensity scores are widely used in cohort studies to improve performance of regression models when considering large numbers of covariates. Another type of summary score, the disease risk score (), which estimates disease probability conditional on nonexposure, has also been suggested. However, littl...
The Stanford Healthcare (SHC) study cohort consists of 99,909 patients who underwent 99,909 echocardiogram studies between 2000 and 2019. The mean age at the time of echocardiogram study was 59.9 ± 17.7 years, 44.3% were women, and 56.5% self-identified as White. Demographic ...

Whether progression or regression in LAV has prognostic value in patients with ESRD is still unknown. The prognostic value for CV events of changes in ... Tripepi,Benedetto,...
In Canada, few studies have used longitudinal data to investigate the causal links between socio-economic resources and mental health. Using fixed-effects models applied to three waves of the Canadian Work, Stress and Health Survey, researchers found that subjective financial strain was associated with...

removing the effects of unobserved time-invariant confounders. We used data from three to four waves of an occupational Japanese cohort survey, focusing on 31,382 observations of 9741 individuals who participated in at least two consecutive waves. We estimated mean-centered fixed effects models to...
