There's a new study out, which is much more comprehensive than earlier ones,

Expect physicians to stop prescribing hydroxychloroquine and chloroquine for Covid-19 patients.
The study examines 96,032 patients, of which 14,888 received hydroxychloroquine or chloroquine and the rest were considered the control group. They only included people who started on the drugs within 48 hours of entering the hospital, and measures of the severity of the disease were similar in the control group and the groups that took the drugs.
I'll just quote results for those who took hydroxycholoroquine without an antibiotic. Results are a little better for those who just took chloroquinine and a little worse for those who combined the drugs with antibiotics (macrolides in the paper).
9.3% of the people who didn't take hydroxychloroquine or chloroquine died, and 0.3% suffered ventricular arrhythmias.
For those who took hydroxychloroquine alone, 18% died and 6.1% suffered ventricular arrhythmias.
Does this mean that people like President Trump who are taking hydroxychloroquine as a prophylaxis are more likely to die? Maybe so, maybe not. There's not enough data out there to know. I sure wouldn't take the stuff. He and everyone around him should wear masks instead.
Aside: Anyone like Friendly Fred who's interested in comorbidities should look at Table 1 in the Lancet paper (linked above). 61% of the people who died were obese.
