| Test 3 | NA | NA | 0.003, 0.48 | NA | NA |
| Test 4 | NA | NA | NA | NA | 0.2 |
| Test 5 | NA | NA | NA | NA | 0.2 and 0.6 for suture and metopic/anterior fontanelle, respectively. Closure by 24 months. |
“E” refers to elastic modulus, “υ” refers to Poisson’s ratio and “NA” indicates no change from the Baseline model values.
