Right ventricular outflow tract function in chronic heart failure.
Article in Indian heart journal, 2016. 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
backgroundHeart failure (HF) is a common, progressive, complex clinical syndrome and a subset of HF patients has symptoms out of proportion to the resting hemodynamics and left ventricular ejection fraction (LVEF). Right ventricular (RV) function is a powerful prognostic factor in HF, but assessing it is a challenge because of the right ventricle's complex geometry.
objectiveThe aim of this study was to investigate the clinical application value of RV outflow tract (RVOT) function measured by transthoracic echocardiography in HF patients.
methodWe prospectively investigated 36 chronic HF patients with dilated heart and LV systolic dysfunction and 21 healthy control subjects (normal ventricular function and ECG, and no cardiac risk factors). In addition to clinical and conventional echocardiographic parameters, RVOT size and fractional shortening (RVOT-FS) parameters were analyzed.
resultsThe RVOT-FS was less in HF patients than healthy controls (18.8±15.7 vs 55.8±6.7, p<0.001) and correlated positively with TAPSE (r=0.814, p<0.001) and inversely with SPAP (r=-0.728, p<0.001) and functional capacity (r=-0.842, p<0.001). There was a statistically significant difference in RVOT-FS among the HF subgroups with regard to NYHA functional capacity (p<0.001), although there was no statistically significant difference with regard to LVEF.
conclusionAlthough the apparent discordance between LVEF and the degree of functional impairment in HF is not well understood, it may be explained in part by alterations in RV function. We found that the RVOT-FS was a noninvasive and easily applicable measure of RV function and might be used for a comprehensive evaluation and follow-up of HF patients with a combined assessment of RV by other RV parameters.
