@ed709062 So, I'd be interested to know what the background rate of impaired lung function in the population was, pre-COVID - is 11% of people who've had mild-COVID 10x worse than the background rate? 100x worse? Same as the background rate? I have no idea, and I can't find any info on this in the study at a quick search.
@7af24c68 The study says it uses GLI reference points for the DLCO LLN. Searching for `GLI DLCO` that turns up the study, which assigns 5%-ile as the LLN threshold, so roughly double the normal rate.
