Estimated dietary sodium intake in peritoneal dialysis patients using food frequency questionnaires and total urinary and peritoneal sodium losses and assessment of extracellular volumes.
Article in European journal of clinical nutrition, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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
backgroundPeritoneal dialysis (PD) patients are advised to restrict sodium intake. For best use of resources, rapid screening tools are required for dietary assessments to allow for targeting of patients. We wished to evaluate the usefulness of food frequency questionnaires (FFQ) for estimating dietary sodium.
methodsSodium intake was estimated using the Derby Salt Questionnaire (DSQ), and Royal Free Sodium Questionnaire (RFSQ). Body composition was determined by bioimpedance.
results90 peritoneal dialysis patients, 52 men (57.8%), mean age 62 ± 15.8 years, were asked to complete the DSQ and RFSQ questionnaires. 88 completed one or more questionnaire, with 87 completing the DSQ and 86 the RFSQ. The median estimated dietary sodium intake 104 (72-145) mmol/day (2.39 (1.64-3.34) g sodium/day) DSQ, and 92 (60-114) mmol/day (2.11 (1.38-2.62) g sodium/day) RFSQ. Younger patients, aged ≤52 years had greater dietary sodium intake compared to those ≥76 years (RFSQ 105.4 (73-129) vs 96 (71-116) mmol/day), p < 0.05. Extracellular water to total body water (ECW/TBW) was greater in those with higher DSQ estimated dietary sodium intake (0.40 ± 0.01 vs 0.39 ± 0.01, p < 0.05). A multivariable model showed that increased dietary sodium intake was independently associated with increased SMM (DSQ odds ratio (OR) 1.17 (95% confidence limits 1.05-1.32, RFSQ OR 1.15 (1.04-1.27, p < 0.05) and raised ECW/TBW (DSQ OR 1.88 (1.22-2.92) p = 0.004, and ECW/height (RFSQ OR 1.42 (1.02-1.98) p = 0.04.
conclusionsBoth questionnaires were acceptable to patients, and the majority were found to be consuming more dietary sodium than recommended. Dietary sodium estimation was associated with SMM and increased ECW.
