Standard Deviation 0.80
2.44 kg
Standard Deviation 0.95

PRIMARY outcome

Timeframe: At the end of the 1st, 6th, 12th week (3 hemodialysis sessions are done every week)

It will be assessed three times at the end of the dialysis session with Visual Analogue. Thirst intensity measured on a Visual Analog Scale with scores ranging from 0 - 10. Thirst increases as the score increases. The high point describes bad outcome.

PRIMARY outcome

Timeframe: At the end of the 1st and 12th week (3 hemodialysis sessions are done every week)

It will be assessed two times at the end of the dialysis session with sample of saliva. Saliva flow rate/minute will be measured. Saliva flow rate/minute is presented with "ml".

PRIMARY outcome

Timeframe: At the end of the 1st and 12th week (3 hemodialysis sessions are done every week)

It will be assessed with "Dialysis Symptom Index". Using this scoring system, the minimum possible total severity score was 0 if none of the 30 symptoms was present and the maximum potential. Score was 150 if all of the 30 symptoms were reported and rated as "very much bothersome". The minimum value is "0" and the maximum value is "150".

SECONDARY outcome

Timeframe: At the end of the 1st and 12th week (3 hemodialysis sessions are done every week)

It will be assessed with Hospital Anxiety and Depression Scale. This scale, which has a two-factor structure is comprised of 14 items. Seven of these items assess the anxiety status and the remaining seven assess depression. Each item is scored on a four-point scale. Total score ranges between 0 and 21 for anxiety and depression. Scores between 0 and 7 indicate normal emotional status.

SECONDARY outcome

Timeframe: At the end of the 1st and 12th week (3 hemodialysis sessions are done every week)

It will be assessed with "Fluid Control Scale in Hemodialysis Patients". the scale had 24 items and three subdimensions,namely, knowledge, behavior, and attitude. The lowest score obtained from the scale was 24 and the highest score was 72, and the higher the score, the greater the compliance of the patients with fluid control.
