Different diuretic properties between tolvaptan and furosemide in congestive heart failure patients with diuretic resistance and renal impairment: a subanalysis of the K-STAR.
Trial report in Heart and vessels, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
We attempted to identify the difference in diuretic properties between tolvaptan (TLV) and furosemide (FUR) in congestive heart failure (CHF) patients with loop diuretic resistance and renal impairment. We investigated 81 CHF patients with loop diuretic treatment and renal impairment included in t he Kanagawa Aquaresis Investigators Trial of Tolvaptan on Heart Failure Patients with Renal Impairment (K-STAR). Predictive baseline factors and their changes during treatment periods were analyzed for correlation with percentage change in urine volume (%ΔUV) after additive introduction of TLV or increasing doses of FUR. Higher urine osmolality at baseline (β = 0.355; p = 0.033) in the TLV group and a lower ratio of blood urea nitrogen to serum creatinine (BUN/Cr, β = - 0.405; p = 0.020) in the FUR group were predictive of higher %ΔUV. Higher Δfree-water clearance (β = 0.667; p < 0.0001) in the TLV group, and higher %ΔBUN/Cr (β = 0.344; p = 0.030), higher %Δurine sodium concentration (β = 0.337; p = 0.037), and lower %Δstroke volume (β = - 0.390; p = 0.017) in the FUR group were correlated with %ΔUV. In conclusion, baseline urine osmolality and change in free-water clearance with additive introduction of TLV and a changing ratio of BUN/Cr with increasing doses of FUR were identified as key clinical parameters related to diuretic response.Trial registration UMIN000009201.
