Differences between the Cooling + Argon and Cooling group TUNEL counts for all seven brain regions and overall.
| Area | Difference in mean TUNEL count (Cooling–Cooling + Argon) | Standard error of the difference | Lower 95% C.I. for difference | Upper 95% C.I. for difference | p value |
|---|---|---|---|---|---|
| Sensorimotor cortex | 22.4 | 23.3 | − 23.5 | 68.4 | 0.338 |
| Cingulate cortex | 25.3 | 23.3 | − 20.7 | 71.3 | 0.279 |
| Thalamus | 10.4 | 23.3 | − 35.5 | 56.4 | 0.655 |
| Caudate | 42.2 | 23.3 | − 3.8 | 88.2 | 0.072 |
| Putamen | 61.0 | 23.3 | 15.0 | 107.0 | 0.010 |
| Internal capsule | 2.4 | 23.3 | − 43.5 | 48.4 | 0.917 |
| Periventricular white matter | 3.5 | 23.3 | − 42.5 | 49.5 | 0.880 |
| Overall | 20.9 | 8.8 | 3.7 | 38.2 | 0.018 |
The overall cell death in 7 regions was reduced in the Argon + Cooling group compared to the Cooling group, with the largest difference seen in the putamen and in the caudate. Bold emphasis indicates statistical significance.
