Fig. 2From: The Interdialytic Creatinine Rise is a novel marker of volume overload and mortality risk in hemodialysis patientsIDCR change with time in 35 hospitalized patients without hemodialysis (Group 1 of Study 1). IDCR is calculated on hospital day 1 and each following day awaiting hemodialysis. The thin lines identify individual patients, with the number of observations (obs total of 84) for the day shown below. The average values of IDCR are shown by the bold squares with the error bars corresponding to the standard deviations. Based on the GEE model, IDCR decreases, changing by − 0.014 per day (95% CI − 0.017, − 0.010; p < 0.001) without HD due to volume gainBack to article page
