1 · What the graph read from it

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.

2 · The registry

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

Purpose: This study aimed to compare the effects of dexmedetomidine (DEX) and propofol on patients undergoing invasive ventilation after off-pump coronary artery bypass grafting (OPCABG) with regard to oxygenation index (OI) (PaO2/FiO2), hemodynamic changes, extubation time, and adverse reactions. Patients and Methods: This single-center retrospective study included 195 patients admitted to the cardiovascular surgery intensive care unit (CVICU) after OPCABG between January 2022 and June 2024. According to the postoperative invasive mechanical ventilation for sedation with only DEX or propofol, the patients were classified into groups D and P. The primary outcome was oxygenation index (OI) before and after extubation. The secondary outcomes included mean arterial pressure (MAP) and heart rate (HR) before and after extubation, extubation time, and adverse reactions after surgery. Results: DEX was significantly associated with an increased likelihood of OI before and after extubation composed to propofol ( Conclusion: DEX may support satisfactory OI, good hemodynamic stability, rapid extubation time, and a lower incidence of adverse reactions for sedation of mechanically ventilated patients following OPCABG surgery compared to propofol, although the difference with OI did not reach the MCID.
