Post-surgical DKA stems from poor glycemic control prior to surgery and perioperative catecholamine usage: unmatched case-control 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
objectiveSurgery is a well-known trigger of Diabetes Ketoacidosis, DKA. Post-surgical DKA is poorly studied in the current literature. This study investigated post-surgical DKA association with poor glycemic control before surgery.
methodUnmatched case–control study sampling all post-surgical DKA cases admitted to ICU during the period from 1st of March 2019 to 1st of December 2022 in King Saud Medical City, Riyadh, Saudi Arabia. The control group comprises all other adult post-surgical subjects admitted to ICU without DKA during the same period. Poor glycemic control was considered when the glycosylated hemoglobin, HbA1C, was equal to or more than 7%. Details of surgery were collected from patients’ records.
resultsFifty-seven post-surgical DKA cases were included and the control group consists of 114 subjects. Poor glycemic control was more frequent among postoperative DKA cases with a statistically significant difference (OR 48.2 95% CI: 12.1 – 267.4; p value < 0.001). Sensitivity analysis of fifty-four pairs of cases and controls matched for age and sex had odds ratio of 48.6 (95% CI: 12.1 – 267.4, p < 0.001). Multivariable logistic regression was done for independent predictor of postoperative DKA. Intraoperative catecholamine and insulin usage along with prolonged duration of surgery were statistically significant predictors (p values < 0.05).
conclusionPost-surgical DKA was ascribed to poor glycemic control. The usage of catecholamine during surgery associated with postsurgical DKA and should be considered in future research.
