In total there were twelve readmissions to hospital due to CHF during the followup period. One patient was readmitted two times during each intervention. The distribution between the interventions was the same, 6 readmissions during the 1.5L/dayintervention and 6 during the 30ml/kg body weight/day intervention. The number ofdays spent in hospital was 42 during the 1.5L/day intervention and 56 during the30ml/kg body weight/day intervention (P=0.30). Analysis of carry-over effects, in regard to the order of the interventions, revealed no such effects.
