Where they differ
From the rowsThe best-graded row, grade C, is a randomized trial of 30 people (2009) and found a worse outcome.

Only the row that found an improvement names athletes or trained people in its population. Only the row that found a worse outcome names men in its population.
The row that found an improvement is newer (2017) than the row that found a worse outcome (2009).
