  1. ^Injury to nerves and spinal cord are grouped with other injuries due to small cells. Cell suppression is indicated where cells are suppressed not due to low cell counts, but to prevent low counts in other cells being re-calculated by subtraction from the total. †p < 0.05 or ‡p < 0.0001 statistical difference between this group and all other claims in chi-square testing.
