Linear regression with the interaction term between sodium intake calculated by the artificial intelligence algorithm (AI-Na; adjusted) and 24-hour urine sodium (UNa) excretion (adjusted R2=0.739; F=18.7; P<.001).
| Linear regression with interaction term | Regression coefficients | SE | P valuea |
| AI-Na (mg; adjustedb) | 0.535 | 0.232 | .03 |
| Furosemide dose (mg) | –2292.009 | 2259.709 | .32 |
| eGFRc (ml/min/1.73m2) | 22.102 | 8.361 | .02 |
| AI-Na (furosemide dose; adjusted) | 1.820 | 1.076 | .11 |
