The linked study concluded the following:
"By administering hydroxychloroquine combined with azithromycin, we were able to observe an improvement in all cases, except one patient who arrived with an advanced form, who was over the age of 86, and in whole the evolution was irreversible. For all other patients in this cohort of 80 people, the combination of hydroxychloroquine and azithromycin resulted in a clinical improvement that appeared significant when compared to the natural evolution in patients with a definite outcome, as described in the literature... The favorable evolution of our patients under hydroxychloroquine and azithromycin was associated with a relatively rapid decrease in viral RNA load...In conclusion, we confirm the efficacy of hydroxychloroquine associated with azithromycin in the treatment of COVID-19 and its potential effectiveness in the early impairment of contagiousness."
