Comparison of “Dissolved” calcium versus different calcium fractions measured for samples where measurements for more than one fraction were supplied in the source data.
| Comparison | n | ρ | p-value | Slope |
|---|---|---|---|---|
| “Dissolved” vs “Total” | 139453 | 0.977 | <0.001 | 1.019 |
| “Dissolved” vs “Total Recoverable” | 17791 | 0.982 | <0.001 | 1.019 |
| “Dissolved” vs “Recoverable” | 9513 | 0.967 | <0.001 | 1.023 |
| “Dissolved” vs “Extractable” | 490 | 0.947 | <0.001 | 0.969 |
| “Dissolved” vs “Soluble” | 267 | 0.977 | <0.001 | 0.998 |
ρ = Pearson’s correlation coefficient.
