Table 1 Results of the linear regressions of sweet-spot times with time to peak strain and end systolic time
From: Can we predict the diffusion "sweet-spot" based on a standard cine?
|  | Mean sweet spot time ± SD (ms) | Slope [95% confidence intervals] | Offset (ms) [95% confidence intervals] | R-squared |

Systolic circumferential | 154 ± 22 | 0.49 [0.30 - 0.68] | -11 [-75 - 53] | 0.75 |
Diastolic radial | 488 ± 56 | 1.33 [0.96 - 1.71] | 40 [-88 - 168] | 0.85 |
Diastolic circumferential | 512 ± 54 | 1.29 [0.91 - 1.67] | 78 [-50 - 206] | 0.84 |
Using time to peak systole | Â | Â | Â | Â |
