Is elabela/toddler a poor prognostic marker in heart failure patients?
Article in Hippokratia. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Elabela/toddler (ELA-32) is a recently identified endogenous apelin receptor ligand. ELA levels are known to rise in heart failure (HF) patients. However, the association between elevated ELA levels and prognosis in these patients remains unknown. We aimed to investigate whether ELA plasma levels are correlated with prognosis in heart failure patients with reduced ejection fraction (HFrEF). Methods: This case-control cross-sectional study enrolled 150 patients, including 73 HFrEF patients and 77 age- and gender-matched healthy volunteers. We collected a blood sample at hospital admission to measure ELA-32 levels. The study endpoint was cardiovascular mortality or HF-related hospitalization. We followed up all patients in the study for a mean of 7.48 ± 2.73 months. Results: In patients with HFrEF, ELA-32 levels were higher than those in controls. The levels of ELA-32 showed a significant increase at advanced New York Heart Association stages. In the receiver operating characteristics curve analysis, a cut-off value of the serum ELA-32 level of 8.25 ng/mL showed a sensitivity of 76 % and specificity of 82 % for predicting the study endpoint [area under the curve: 0.84; 95 % confidence interval (CI): 0.72-0.98; p <0.001]. Cardiovascular mortality (p =0.042) and HF-related hospitalization (p <0.001) were statistically more significant in patients with ELA-32 levels greater than 8.25. Age [Hazard ratio (HR) =1.023; 95 % CI: 0.964-1.230, p =0.039], N-terminal pro-brain natriuretic peptide (HR =1.300; 95 % CI: 1.017-1.874, p =0.017), left ventricular end-diastolic volume (HR =1.142; 95 % CI 1.022-1.547, p =0.028), and ELA-32 ≥8.25 (HR =2.556; 95 % CI: 1.078-3.941, p <0.001) remained independently associated with the risk of study endpoint. Conclusion: For the first time, HF-related hospitalizations and cardiovascular mortality are independently associated with increased ELA-32 levels in patients with HFrEF.
