Table 4. Linear regression between cumulative estimated deficit of phosphorus intake and calcium and phosphate plasma level.

Linear regression procedure r2 F-ratio P
Calcemia vs. cumulative deficit of P intake 0.210 213 <0.001
Adjusted calcemia vs. cumulative deficit of P intake* 0.307 357 <0.001
Phosphatemia vs. cumulative deficit of P intake 0.173 90 <0.001
Adjusted phosphatemia vs. cumulative deficit of P intake** 0.365 257 <0.001

* Adjusted on first day calcium plasma level. ** Adjusted on first day phosphate plasma level.
