  • Blazer A. (@ablazermd) “Would we expect to see a significant difference between eos levels of 150? Eos > 300 is generally felt to be the relevant cut off for favouring the use of ICS. (However this was a small proportion of pts in this study).” August 27, 2020. 8:02pm Tweet
  • Stanbrook M. (@drstanbrook). “We actually know from other studies that the effect is continuous, not dichotomous. Higher eos = greater ICS response. Supplement has a figure showing exactly that. “August 27, 2020. 8:57pm Tweet.

  • Blazer A. (@ablazermd) “Part of what is novel in this study is the two different ICS doses - why not compare between them? They actually state "the trial was not powered to detect a significant difference between the triple-therapy regimens." Why not? It was to compare between the other grps.
