Freely Filtered 033: The Roxadustat Statistics shenanigans

On April 6, 2021 Fibrogen announced that the analysis of the cardiovascular outcomes was adjusted after the data was unblinded.

Importantly for this NephJC discussion, the previously impressive MACE and MACE+ advantage for incident dialysis is no longer found. Roxadustat remains non-inferior in all outcomes, though the confidence intervals have widened.
