Fig 1 Proportion of participants with reflux of 0.5 seconds or more duration in either leg at individual vein segments, by sex (adjusted for age). CFV, common femoral vein; SFV, superficial femoral vein; a.k. POP, above knee popliteal; b.k. POP, below knee popliteal; LSV, long saphenous vein; lower LSV, lower thigh LSV; SSV, short saphenous vein.
