Detecting if change in end-tidal carbon dioxide signifies change in cardiac output for the prediction of fluid responsiveness in patients undergoing major abdominal oncosurgery: An observational study.

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 and Aims: Changes in end-tidal carbon dioxide (ΔETCO Methods: We conducted a prospective study in 22 adults undergoing major abdominal surgery between April 2022 and January 2023. Cardiac output and stroke volume were monitored using the FloTrac™ system with a Vigileo or EV1000 monitor. Patients were mechanically ventilated with a tidal volume of 8 mL/kg predicted body weight and a respiratory rate of 12-16 breaths/min. An intravenous bolus of Ringer's lactate (4 mL/kg actual body weight over 10 minutes) was administered when haemodynamic parameters suggested hypovolaemia. Patients with a ΔCI ≥10% were classified as fluid responders, with ΔCI serving as the reference standard. ΔETCO Results: ΔETCO Conclusion: ΔETCO
