Table 3. HRR in patients with T2* < 20 ms vs. those with > 20 ms.

Characteristics	T2* < 20 ms (n = 18)	T2* > 20 ms (n = 38)	p
HRR 1	30.5 ± 6.0	31.5 ± 12.4	0.70
HRR 2	49.6 ± 12.6	52.7 ± 14.9	0.42
HRR 3	54.7 ± 12.1	58.5 ± 14.6	0.80
HRR 4	57.6 ± 11.7	61.0 ± 13.2	0.33
HRR 5	57.8 ± 12.0	62.2 ± 14.3	0.23

Values are expressed as mean ± standard deviation. p < 0.05 value is significant. In all cases, differences were not statistically significant. HRR, heart rate recovery. One way analysis of variance, Mann-Whitney U-test, Independent samples t-test.
