Relationship between baseline mature adipocyte cell size (x axis) and change in adipocyte size (y axis) in response to weight gain. •, data from women; □, data from men. (A) Abdominal s.c. adipocytes vs. change in abdominal adipocyte size. The relationship is significant for women (r = −0.64, P = 0.02) but not for men (r = 0.23, P = 0.43). (B) Femoral adipocytes vs. change in femoral adipocyte size. The relationship is significant for women (r = −0.64, P = 0.02) and is of borderline significance for men (r = −0.52, P = 0.057).
