Effectiveness of Dexamethasone in Reducing Arrhythmia in Patients Undergoing Coronary Artery Bypass Grafting.

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
Introduction Coronary artery bypass grafting (CABG) carries the risk of postoperative arrhythmias. Our study focusses on the efficacy of dexamethasone in both on-pump CABG (ONCAB) and off-pump CABG (OPCAB). Methods This single center randomized control trial was conducted from July 1st, 2018 to January 20th, 2019 in patients undergoing conventional ONCAB and OPCAB at the National Cardiovascular Center Harapan Kita (NCCHK). All arrhythmia incidents were recorded postoperatively with routine monitoring done every hour until the patient was discharged. Results One hundred and twenty patients were included in the study and arrhythmias occurred in 24.2% of patients. In the ONCAB groups, there was an association between dexamethasone versus placebo in reducing the incidence of arrhythmias (p = 0.02; OR 0.23 [0.064-0.831]). However, in patients who underwent OPCAB, there was no association between dexamethasone administration and the incidence of arrhythmias (p = 0.347; OR 0.55 [0.157-1.931]). Patients on dexamethasone in both ONCAB and OPCAB groups showed a significant decrease in IL-6, CRP, and procalcitonin (p = 0.001 for all). Overall, arrhythmic subjects had significantly higher levels of inflammatory markers IL-6 (p = 0.013), CRP (p = 0.025), and procalcitonin (p = 0.001). Conclusion Dexamethasone reduced postoperative arrhythmias, likely by modulating systemic inflammation, as shown by the decrease in inflammatory markers in ONCAB patients compared to those given a placebo.
