We have adjusted accordingly. We hope now we can give a clearer explanation about the motivation of this study.
P2 L69: The aim stated here does not follow the logic of the preceding statements in the paragraph, i.e., what does comparing BC methods have to do with lack of healthcare or technology? Is the focus then on finding low cost, easy to apply methods? The aim (and intent) of the study seems too simplistic as stated here – merely comparing methods. How would the results be applied to the healthcare situation in Mexico? These topics should be tied together or an alternative motivation needs to be presented.
