Post-acute sequelae of COVID-19 symptom phenotypes and therapeutic strategies: A prospective, observational study.

Patients in symptom Clusters 2/3 were more likely to be represented in Therapy Groups B and C, though this did not reach statistical significance (P=0.052). o For the 12-month outcomes, e.g., "improved with therapy", it may be interesting to compare Therapy group B and C vs A, while adjusting for cluster 2 and 3 dummy variables as well as severity of disease + testing for interaction between the therapy dummy variables (Therapy group B and C) and cluster dummy variables.
