Fig. 3. Depiction of the outlines of the medial margin of transversus abdominis muscle (TT’, red line); lateral margin of rectus abdominis muscle (RR’, blue line); LL’, linea alba; RL, distance between lateral margin of rectus abdominis and linea alba; TL, distance between the medial margin of transversus abdominis and linea alba. The black dotted lines represent the mean TA distance (RL–TL) at various levels (a, xiphisternum; b, midway between xiphisternum and umbilicus; c, umbilicus; d, arcuate line; e, midway between arcuate line and pubic symphysis). The positive distances indicate overlap and negative distances indicate lack of overlap. The distances in mm are converted to cm for the sake of ease and clarity.
