Postoperative mortality in patients requiring home oxygen therapy: a nationwide hospital-based database study.
Article in Journal of anesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo identify the postoperative mortality in patients requiring home oxygen therapy (HOT).
methodsThis descriptive study used a nationwide hospital-based database constructed by JMDC Inc. (Tokyo, Japan). Patients aged ≥ 18 years requiring HOT who underwent surgery between January 2014 and June 2022 were included. The study outcomes were in-hospital and 30-day postoperative mortality rates and other complications. We established a non-HOT group matched by age, sex, procedure, and surgical urgency for contrast and analyzed mortality in subgroups based on the reason for HOT, surgical department, and urgency.
resultsAmong the 3349 patients receiving HOT who underwent surgery, 293 (8.7%) in-hospital mortalities and 213 (6.4%) 30-day mortalities were reported. Postoperative pulmonary complications were observed in 359 (10.7%) patients, and 227 (6.8%) had non-respiratory complications. Furthermore, 123 (3.7%) in-hospital mortalities and 74 (2.2%) 30-day mortalities were also reported in the non-HOT group (3323 patients). The subgroup analysis indicated no significant differences in mortality or complications based on the reason for HOT. Higher mortality rates were reported in gastroenterology (9.3%), dermatology (14.7%), respiratory (11.8%), otolaryngology (36.5%), and neurosurgery (16.3%) departments. In-hospital and 30-day mortalities for emergency surgeries in the HOT group were 17.3 and 13.4%, respectively.
conclusionAmong patients requiring HOT, in-hospital and 30-day mortalities were 8.7 and 6.4%, respectively. In addition, emergency surgeries may contribute to higher postoperative mortalities. Future research should identify specific mortality risk factors and develop perioperative management strategies to reduce these risks.
