Multivariate predictors of hemoglobin in non-anuric subjects undergoing peritoneal dialysis

	B	SE	95% CI of B	β	P-value
Constant	15.141	0.983	13.186 to 17.095		<0.001
Log iron saturation	2.521	0.718	1.093 to 3.948	0.332	0.001
Log total IS	−2.093	0.617	−3.320 to −0.866	−0.320	0.001

Notes: R=0.507, R²=0.257, adjusted R²=0.24. Excluded factors: albumin, high-sensitivity C-reactive protein, gender, angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker use, ferritin, residual renal creatinine clearance.

Abbreviations: β, standardized regression coefficient; B, unstandardized regression coefficient; CI, confidence interval; IS, indoxyl sulfate; SE, standard error of the estimate.
