The effect of sodium restricted diet on the prognosis of heart failure patients: a systemic review and meta-analysis.
Review in Frontiers in cardiovascular medicine, 2026. 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
Aims: To evaluate whether a sodium restricted diet can improve the prognosis of HF patients. Methods: Retrieve for randomized controlled trials (RCTs) on sodium restricted diets for HF patients from PubMed, Web of Science, Cochrane Library and Embase, with a retrieval period from the establishment of databases to July 2025. Two researchers independently conducted literature screening using RevMan 5.4 and evaluated the quality using Cochrane risk of bias tool. Finally, StataMP 18 was used for meta-analysis. Results: 16 RCTs were included, with 2260 patients. The meta-analysis results showed that compared with the control group, the sodium restricted diet group had significantly increased all-cause mortality rate (RR 1.50 [95%CI: 1.05-2.14] I Conclusion: Although sodium restriction may improve the quality of life of HF patients, it is not associated with a reduced risk of readmission or lower the serum NT-proBNP level; for HFrEF patients receiving diuretic therapy and fluid restriction, the sodium restricted diet is associated with an increased risk of all-cause mortality and HF readmission.
