Variables	Unstandardized coefficients		Standardized coefficients	t	P value
	B	SD	β
Constant	21.89	1.25	-	17.58	< 0.001
History of corticosteroids	8.93	2.13	0.39	4.20	< 0.001

¹Restricted to the 81 patients (72.32% of the overall sample) for whom complete information on age, diabetes status, weight, height, serum hemoglobin, albumin levels, presence of predialytic gastrointestinal symptoms, peritoneal dialysis type, duration of peritoneal dialysis, daily dialysate volume, history of corticosteroid use, daily dosage of pills, residual renal Kt/V, peritoneal Kt/V, total Kt/V were available. Adjusted for history of corticosteroid use (yes = 1, no = 0).
