Balanced crystalloid versus saline for resuscitation in adult sepsis: a systematic review and meta-analysis.
Synthesis in Frontiers in 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
Background: Fluid resuscitation is the cornerstone of sepsis management, however, the choice between balanced crystalloid solutions and normal saline remains debated. This meta-analysis aimed to compare the efficacy of balanced solutions versus saline for fluid resuscitation in adult patients with sepsis. Methods: A systematic literature search was performed in PubMed, Embase, Scopus, and other relevant sources. Retrieved studies were rigorously screened according to predefined inclusion and exclusion criteria. Data from the included studies were extracted for analysis. The primary outcome was defined as mortality rate. Secondary outcomes included acute kidney injury (AKI), hyperchloremia, renal replacement therapy (RRT), ICU-free days, ventilator-free days, vasopressor-free days. The study protocol was registered with PROSPERO (CRD420261368142). Results: A total of eight studies (8,173 patients; 4,056 assigned to balanced solutions, 4,117 to saline) met the inclusion criteria. In the primary analysis restricted to seven randomized controlled trials, balanced solutions were associated with significantly lower mortality than saline (RR 0.92; 95% CI 0.86-0.98; Conclusion: In adult patients with sepsis, treatment with balanced crystalloid solutions for fluid resuscitation significantly reduces mortality (moderate certainty), decreases kidney-related adverse events, and better maintains electrolyte balance, thereby improving patient outcomes. These findings support the preferential use of balanced crystalloids over saline in this population.
