The best bit about LyX is using it to format LaTeX tables nicely.
When writing my thesis I used LyX but found myself creating more and more ERT (what LyX calls raw LaTeX code). I eventually just started using a text editor. However, I still do tables in LyX and copy them over -- such a pain to insert a column otherwise...
Of related interested, and possibly the only paper that has reached the NEJM with a magician as an author, is this paper that describes David Blane's physiology having spent 44 days fasting in a box: http://www.nejm.org/doi/full/10.1056/NEJM200511243532124
If the authors were using kg/m^-1 instead of kg/m^-2 with the given information (96.8 kg; BMI, 30.2 kg m−1; height not provided), the patient would need to be over 3m (nearly 10 ft) tall. This seems unlikely. If it were true, it would probably make for an even more interesting case report.
