Figure 5. Hematoma volumes (ml) and percentage deviations (%) for regular, irregular and multilobular hemorrhages calculated by gold standard, formula 1/2ABC and 2/3SH.

Figure 5

(A) the comparison of three methods in hematoma volume was statistically indistinguishable (P>0.05); (B) formula 1/2ABC and 2/3SH underestimated hematoma volume by −18.51(−28.20, −5.80)% and −15.56(−25.85, 3.38)% for regular hemorrhage, −9.26(−20.75, 5.19)% and −3.23(−15.78, 6.17)% for irregular hemorrhage, respectively. However, for the multilobular shaped hemorrhage, the formula 1/2ABC underestimated by −8.53(−16.73, 4.25)% and 2/3SH overestimated only by 1.96(−6.37, 9.68)%.
