On another note regarding journal articles, reading an abstract or a summary only, amounts to taking what is said as gospel. That is very dangerous! As anyone familiar with research (I mean truly familiar, not a couple of years of pre-med research) knows, much of what is in the literature is erroneous, and even more of the conclusions are based on faulty analysis of faulty and incomplete studies, with data that has little (if any) statistical error analysis. Thus, it is important to read articles with a questioning mind. That means physicians and medical students with precious little time to read journal articles should be very selective about the articles that they read, and read them critically. That means to look at how the studies were done, and question whether the conclusions follow logically from the data and analyses presented. Quite often conclusions and interpretation of data are on very shaky ground and should be regarded as such. Here is where the math comes in. In a lot of studies, at least an appreciation of mathematics (statistics, calculus, complex variables, whatever may be the case) is needed to be able to understand a body of work and so to be able to view it critically and put it in its proper perspective, i.e. whether or not and how you want to use that information in your daily practice, be it medical research or patient care.
