Effectiveness of intraoperative nicorandil in patients with a history of ischemic heart disease undergoing high-risk noncardiac surgery: a retrospective cohort study.
Article in Journal of anesthesia, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeNicorandil is occasionally administered to prevent myocardial ischemia during the perioperative period in patients with ischemic heart disease (IHD); however, its effectiveness has not been clarified. In this study, we examined the effectiveness of intraoperative nicorandil administration in noncardiac surgery.
methodsWe identified patients with a history of IHD who had undergone high-risk noncardiac surgery between April 2015 and March 2020 from a nationwide in-patient database in Japan. The patients were divided into those who received nicorandil (nicorandil group) and those who did not (control group). The primary outcome was the 30-day in-hospital mortality. The secondary outcome was major adverse cardiovascular events (MACE), defined as the composite outcome of the 30-day in-hospital mortality, acute myocardial infarction, percutaneous coronary intervention, and coronary artery bypass grafting. One-to-one propensity score matching was performed. The outcomes were analyzed using a Cox proportional hazards model.
resultsOf 8037 patients, 2886 received nicorandil during surgery. After propensity score matching, 2554 pairs were analyzed. There was no significant difference in the 30-day in-hospital mortality (26 [1.02%] vs. 36 [1.41%]; hazard ratio [HR] 1.36; 95% confidence interval [CI] 0.82-2.26; P = 0.229) or incidence of MACE (42 [1.64%] vs. 55 [2.15%]; HR 1.24; 95% CI 0.86-1.93; P = 0.216) between the control and nicorandil groups.
conclusionThe findings of this study suggest that intraoperative nicorandil administration is not associated with the 30-day in-hospital mortality in high-risk noncardiac surgery.
