Significance and prognostic impact of v wave on pulmonary artery pressure in patients with heart failure: beyond the wedge pressure.
Observational study in Heart and vessels, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundA v wave on pulmonary artery wedge (PAW) pressure sometimes augments and appears on pulmonary artery (PA) pressure wave in patients with heart failure (HF). However, the significance of PA v wave in HF remains to be elucidated.
methodsWe retrospectively analyzed pressure waveforms in 61 HF patients (left ventricular ejection fraction 35 ± 15%). On the PAW and PA pressure waveforms, mean pressure as well as peak and amplitude of v waves (ampPAWv and ampPAv, respectively) were measured. Occurrence of worsening HF and cardiac death was recorded for 2 years after the catheterization.
resultsThe ampPAWv did not correlate with ampPAv. When the patients were divided into 4 groups: I (high-ampPAWv/high-ampPAv), II (high-ampPAWv/low-ampPAv), III (low-ampPAWv/high-ampPAv), and IV (low-ampPAWv/low-ampPAv), the prevalence of group III was low (I: 13, II: 17, III: 4, IV: 27). Mean pressures of PAW and PA were similarly elevated in groups I and II. Cardiac index was lowest (I: 2.0 ± 0.4, II: 2.8 ± 0.6, III: 2.2 ± 0.2, IV: 2.4 ± 0.6 L/min/m
conclusionsPA v was observed mainly in patients with augmented PAW v wave and decreased cardiac index, suggesting an advanced stage of HF. Moreover, augmented PAv was associated with worse outcome in HF patients.
