Comparative Mortality Rates of Vasoconstrictor Agents in the Management of Hepatorenal Syndrome: A Systematic Review and Meta-Analysis.
Review in Cureus, 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
Hepatorenal syndrome (HRS) is an acute complication of advanced liver disease, which manifests with a rapidly progressive decline in kidney function. Though pharmacological treatment has been recently advanced, there are still high mortality rates. The study compares the mortality rate in patients using different vasoconstrictor agents in the management of HRS. A complete literature search was done in the following databases: PubMed, Cochrane Library, PubMed Central (PMC), and Multidisciplinary Digital Publishing Institute (MDPI). Studies were included according to previously established criteria, in which all studies reporting on adult patients with HRS treated with vasoconstrictor agents were eligible. The data extracted were analyzed with a random-effects model to express variability between studies, and the principal measure was the risk ratio (RR) for mortality. Of the 8,137 studies identified, 29 met the inclusion criteria. In the meta-analysis, vasoconstrictors, mainly terlipressin, significantly improved renal function and decreased the need for renal replacement therapy (RRT) versus placebo. However, a significant impact on mortality was lacking (0.94 (0.84-1.06), p = 0.31). The subgroup analysis found that mortality rates were not significantly different between vasoconstrictors, whether used in combination with or without albumin (0.97 (0.77-1.23), p = 0.79, and 0.98 (0.79-1.21), p = 0.86). Global heterogeneity was low, indicating consistent results in the studies. Vasoconstrictors are helpful in managing HRS, with improvement in renal function and reduction in RRT requirements. However, the effect on mortality was small and nonsignificant. Such findings support the use of terlipressin in HRS management; concomitantly, they emphasize the need for personalized treatment strategies and future research to find alternative therapies that may be more effective for improved survival results with fewer side effects.
