<p>The choice of study type is good, but the content of the method paragraph is not satisfied. Fo example, they didn't mention where/when/how to collect the data, the data analysis??&nbsp;</p><p>In the result, I think they must show the results of comparison, according to the risk factor. The number of sample is not well shown (418 or 100??)</p><p>There is no relation with result and conclusion : the "tuberculosis treatment" is not mentioned in the result</p>
