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: The establishment of pneumoperitoneum has impacts on patient's cardiovascular function. In this study, the respiratory variation of inferior vena cava (IVC), stroke volume (SV) index, and other parameters was monitored to determine how the pneumoperitoneum affects the patient's hemodynamic and acknowledge how to resolve it. Materials and Methods: Fifty-five patients were randomly divided into Group A (8 mmHg), Group B (10 mmHg), Group C (12 mmHg), Group D (14 mmHg), and Group E (12 mmHg, infusion with 7 mL/kg crystalloid solution). The parameters including IVC variability, SV index, mean artery pressure (MAP), heart rate (HR), cardiac output index (CI), and airway pressure were measured, to compare the changes before and after pneumoperitoneum. Results: Among Group A, Group B, Group C, and Group D, there were no significant differences in patients' prepneumoperitoneum information. Compare with prepneumoperitoneum, the difference in IVC variability, SV index, MAP, HR, CI, and airway pressure was statistically significant ( Conclusion: The establishment of pneumoperitoneum could increase the patient's IVC variability and reduce SV index, and with the increase of pressure, IVC variability had an increasing trend, SV index had a decreasing trend. Fluid transfusion could reduce the relative influence of the pneumoperitoneum.
