This is why people shouldn't trust the media to explain science.

If you actually read the article, http://subject.med.wanfangdata.com.cn/UpLoad/Files/202003/43f8625d4dc74e42bbcf24795de1c77c.pdf, they state they only look at mild cases. They only had one person become severe. Everyone else left the hospital in 9 days max.

Hydroxychloroquine in the other studies is being used on SICK people, ones who are in the hospital for weeks. It's being used on intubated/struggling patients. https://www.medrxiv.org/content/10.1101/2020.03.18.20038190v1

They're not even looking at decompensation because they only had one person decompensate in this study. They're looking at viral load. Other reports have shown that a small percentage of people still have detectable viral loads after leaving the hospital.

TLDR this study looks at not-very-ill people for a short period of time looking at viral load whereas the other studies where the drug shows effect looks at people who actually need serious treatment and their clinical outcome.

Apples and oranges, guys.
