Table 3. Concordance correlation coefficient, Pearson (precision) and accuracy (bias correction factor) of the X1 PRO and HT IVOS CASA devices in evaluating sperm concentration, TM, and PR compared to MSA.
| Device | Concordance correlation coefficient | Pearson (ρ) | Bias correction factor (Cb) | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Concentration | TM | PR | Concentration | TM | PR | Concentration | TM | PR | |
| X1 PRO (n=101) | 0.96 | 0.93 | 0.91 | 0.96 | 0.94 | 0.92 | 0.99 | 0.99 | 0.99 |
| HT IVOS CASA (n=100) | 0.97 | 0.89 | 0.92 | 0.97 | 0.92 | 0.93 | 0.99 | 0.97 | 0.99 |
PR: progressive motility, TM: total motility, MSA: manual semen analysis.
