No need to read Chinese, the abstract is on page 2. Conclusion: at current trial size no better than placebo. More study is needed to tease out an effect, if there is any.
By now everybody should know that the successful dosis is 2x500mg per day for 10 days. Not 1x 400mg per day, which is the old dosis for Malaria prevention. This dosis needs at least 2-3 weeks to be effective (saturate the cell membranes with zinc), and by then the infection is already over. And the Chinese treatment plan contained much more.
