  1. Table 5a) shows the association between convective volume and the occurrence of IDH without adjustment, and b) shows the Odds ratio after adjustment for relevant parameters.
  2. The groups of convective volume were defined as follows: Group 1: 0 to 7.53 liters, Group 2: 7.54 to 14.8 liters; Group 3: 14.9 to 16.96 liters; Group 4: 16.97 to 18.9 liters; Group 5: 19.1 to 21 liters, and Group 6: 21.1 to 30 liters.
