Echocardiographic Evaluation of Central Venous Pressure Using Inferior Vena Cava Characteristics: An Estimate Guide for Right Atrial Pressure in Intensive Care Unit.
Article in Journal of cardiovascular echography. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Central venous pressure (CVP) is a good approximation of right atrial pressure (RAP), which in turn is a major determinant of right ventricular filling. The inferior vena cava (IVC) is a compliant vessel whose size and shape vary with changes in CVP. IVC diameter and Collapsibility Index (CI) assessed by echocardiography are used as indirect indicators for the estimation of RAP. Aim of the Study: To evaluate the correlation between IVC echocardiographic characteristics and CVP and RAP and the value of assessment of IVC as a guide for the status of the right side of the heart. Patients and Methods: A total of sixty patients (male and female) above 18 years of age, who were admitted in the intensive care unit, were enrolled in this single-center, descriptive cross-sectional study. Echocardiographic assessment of IVC hemodynamics (IVC expiratory [IVCe] and inspiratory [IVCi] diameters and IVC-CI) were carried out. In addition to standard echocardiographic examination, right heart function measurements (Tricuspid annular plane systolic excursion [TAPSE] and right atrial [RA] area) in spontaneously and mechanically ventilated patients were done. Results: The average age of the patients was 62 years (18-80 years). Overall, 45% ( Conclusions: There is a linear relationship of IVC-CI with TAPSE but an inverse relation with RA area. Evaluation of IVC diameter and its CI is an easy and noninvasive method to estimate CVP and RAP and so evaluate right heart performance of critically ill patients. Its use is more helpful in patients who are spontaneously breathing than those who are mechanically ventilated.
