Results of Multiple Linear Regression Analysis to Identify the Factors That Were Associated with the Changes in Flicker ERG Amplitude at 1 Week after the Surgery Compared with Preoperative Values (%)
| Independent Variables | β | P |
|---|---|---|
| Age (yrs) | 0.119 | 0.536 |
| Sex (male/female) | 0.261 | 0.170 |
| Axial length (mm) | –0.037 | 0.846 |
| Operation time (min) | 0.002 | 0.993 |
| Baseline flicker ERG amplitude (μV) | –0.560 | 0.004∗ |
The standardized partial regression coefficient (β) and P values are calculated for 5 independent variables, which were associated with the changes in flicker ERG amplitude at 1 week after the surgery compared with preoperative values (%).
ERG = electroretinography.
∗
P < 0.05 was considered significant.
