Table 1 Clinical characteristics of the samples including erectile dysfunction (ED) patients and healthy controls.
| ED patients (n=78) | Healthy controls (n=32) | P value | |
|---|---|---|---|
| Age | 36.77±10.93 | 34.31±8.75 | 0.261 |
| IIEF-5 | 14.88±4.14 | 23.87±1.24 | |
| Fasting sugar, mmol/L | 4.65±0.58 | 4.43±0.51 | 0.059 |
| Testosterone, nmol/L | 15.67±4.57 | 16.90±3.76 | 0.151 |
| Triglycerides, mmol/L | 1.30±0.47 | 1.44±0.45 | 0.154 |
| Total cholesterol, mmol/L | 4.18±0.96 | 3.87±1.04 | 0.139 |
| PSV max, cm/s | 30.66±10.34 | 42.33±7.65 | |
| EDV, cm/s | 2.11±2.25 | −1.45±1.91 | |
| SWE min, kPa | 11.66±4.98 | 8.08±1.58 | |
| ED – erectile dysfunction; IIEF-5 – the five-item version of the International Index of Erectile Function; PSV – peak systolic velocity; EDV – end-diastolic velocity; SWE – shear wave elastography. | |||
