Quality indicators and development targets in the national clinical quality registries in cancer care and screening.

Background: The Danish clinical quality registries monitor and improve the quality of care, using quality indicators and defined development targets referred to as 'standards'. This study aims to investigate the fulfilment of standards in the Danish clinical quality registries in cancer care and screening.

Methods: Data was included from annual reports in the 27 Danish clinical quality registries in cancer care and screening.

Educational status affects prognosis of patients with heart failure with reduced ejection fraction: A post-hoc analysis from the WARCEF trial.

Aims: The influence of social determinants of health (SDOH) on the prognosis of Heart Failure and reduced Ejection Fraction (HFrEF) is increasingly reported. We aim to evaluate the contribution of educational status on outcomes in patients with HFrEF.

Methods: We used data from the WARCEF trial, which randomized HFrEF patients with sinus rhythm to receive Warfarin or Aspirin; educational status of patients enrolled was collected at baseline.

Misuse of multinomial logistic regression in stroke related health research: A systematic review of methodology.

Multinomial logistic regression (MLR) is often used to model the association between a nominal outcome variable and one or more covariates. The results of MLR are interpreted as relative risk ratios (RRR) and warrant a more coherent interpretation than ordinary logistic regression. Some authors compare the results of MLR to ordinal logistic regression (OLR), irrespective of the fact that these estimate different quantities.
