Effects of salt reduction education from a salt questionnaire on inter-dialysis weight gain in patients on hemodialysis.
Article in Clinical and experimental nephrology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHeart failure is the leading cause of death in patients undergoing hemodialysis (HD), with fluid overload being the most common cause. Therefore, it is important for patients undergoing HD to reduce salt intake. We recently developed a highly accurate and simple self-administered salt questionnaire. Using this salt questionnaire, we aimed to determine whether salt intake and inter-HD weight gain decrease when patients with HD are instructed to reduce their salt intake.
methodsSeventy-eight outpatients at a maintenance HD facility were assessed for dietary salt intake using a salt questionnaire. After one month of dietary guidance, salt intake was assessed again using the salt questionnaire.
resultsThe mean age of the patients was 72.2 ± 11.9 years; 47 (60.3%) were men, 23 had diabetic nephropathy as the primary disease, and the median HD vintage was 74 months. Salt intake significantly decreased from 8.41 ± 2.43 g/day before the salt questionnaire intervention to 7.67 ± 2.60 g/day after the intervention (p = 0.010). Changes in salt intake before and after the intervention were significantly positively correlated with changes in weight gain before the start of HD sessions with an interval of 2 days (r = 0.24, p = 0.037). Furthermore, changes in salt intake significantly and positively correlated with changes in weight gain after adjusting for age, sex, and dry weight.
conclusionThe salt questionnaire may be an effective tool for reducing salt intake and controlling weight gain during HD.
