Combined systolic velocities using tissue Doppler imaging could predict the severity of cirrhosis: a prospective cohort study.
Article in Cardiovascular journal of Africa. 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
aimRecent research has demonstrated that the contractile characteristics of the right ventricular outflow tract (RVOT) play a significant role in right ventricular function. Pulmonary annular motion velocity (PAMVUT) is a reliable marker of RVOT function. Also, combined systolic velocity [PAMVUT added to tricuspid annular systolic velocity (St)] has been revealed as a suitable parameter for right ventricular systolic function. In this study, we examined the association between the severity of the illness in cirrhotic patients and the combined S velocities (CSV).
methodsSeventy-four patients with cirrhosis went to the echocardiography laboratory of the Cardiology Department in our centre. Traditional echocardiographic measurements, PAMVUT and CSV values were recorded. The Child-Pugh classes of the patients were determined.
resultsReceiver operating characteristic curve analysis demonstrated that a CSV of 23 cm/s constituted the cut-off value for predicting a moderate-to-severe form of cirrhosis with 76% sensitivity and 65.3% specificity (area uder the curve = 0.735,
conclusionCSV values could predict the severity of cirrhosis more precisely than traditional right ventricular systolic function parameters.
