As explained here and here, I temporarily combine the announcements of published papers in one blog to save some time. This is part III, where I focus on ordinal outcomes. Of all recent papers, these are the most exciting to me, as they really are bringing something new to the field of thrombosis and COVID-19 research.
Measuring functional limitations after venous thromboembolism: Optimization of the Post-VTE Functional Status (PVFS) Scale. I have written about our call to action, and this is the follow-up paper, with research primarily done in the LUMC. With input from patients as well as 50+ experts through a Delphi process, we were able to optimize our initial scale.
Confounding adjustment performance of ordinal analysis methods in stroke studies. In this simulation study, we show that ordinal data from observational can also be analyzed with a non-parametric approach. Benefits: it allows us to analyze without the need of the proportional odds assumption and still get an easy to understand point estimate of the effect.
The Post-COVID-19 Functional Status (PCFS) Scale: a tool to measure functional status over time after COVID-19. In this letter to the European Respiratory, colleagues from Leiden, Maastricht, Zurich, Mainz, Hasselt, Winterthur, and of course Berlin, we propose to use a scale that is basically the same as the PVFS to monitor and study the long term consequence of COVID-19.
