This article's a step above garbage. Half of the 11 patients had cancer; another had AIDS and several more had diabetes. Even more importantly, there's no information about how long patients were suspected to be sick before starting hydroxychloroquine+azithromycin. Anti-coronavirus medications don't regrow lungs after they've been already been damaged by coronavirus.
The paper could've been very useful with a paragraph per patient of case history, but as-is it's exceptionally mediocre.
