A randomized controlled trial of L-taurine for fatigue in decompensated cirrhosis.
Trial report in Hepatology communications, 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
backgroundFatigue affects 60%-80% of patients with cirrhosis, yet no universally effective pharmacologic therapy exists. Taurine, an amino sulfonic acid with antioxidant and membrane-stabilizing properties, may address metabolic mechanisms underlying fatigue. We hypothesized that L-taurine supplementation would significantly reduce fatigue severity compared to standard care in patients with decompensated cirrhosis.
methodsThis single-center, parallel-arm, open-label randomized controlled trial enrolled adults with decompensated cirrhosis (Child-Turcotte-Pugh score 7-13) and clinically significant fatigue (Fatigue Assessment Scale score >22) at a tertiary care center in South India. Participants were randomized via block randomization to L-taurine (1000 mg/d) plus standard care or standard care alone for 12 weeks. The primary outcome was the change in the Fatigue Assessment Scale score. Analysis of covariance examined treatment-by-anaemia interactions. Effect sizes were calculated using Cohen's d.
resultsOf 220 randomized patients, 202 completed the study (standard care: n=100; taurine: n=102). The mean FAS change was -6.83±8.70 (standard care) versus -8.08±7.95 (taurine), with no significant difference (mean difference -1.25; 95% CI: -3.55 to 1.05; p=0.288; Cohen's d=-0.15). However, a significant treatment-by-anemia interaction was observed (p=0.009). In patients without anemia (n=41), taurine produced a large treatment effect (-11.90±4.04 vs. -4.57±9.23; p=0.002; Cohen's d=-1.02), whereas patients with anemia (n=161) showed no benefit (p=0.832). Adverse events occurred in 11.8% of patients treated with taurine, all of which were mild.
conclusionsL-taurine did not improve fatigue in unselected patients with decompensated cirrhosis. A post hoc subgroup analysis suggested potential benefit in patients without anemia; however, given the open-label design, small subgroup size, post hoc nature of the analysis, and the inherent limitations of unblinded patient-reported outcomes, this finding should be considered hypothesis-generating. A confirmatory, placebo-controlled trial enrolling patients without anemia is warranted (Clinical Trials Registry India number CTRI/2023/06/054455).
