Nutritional status and postoperative recovery outcomes in patients undergoing orthopedic surgery.

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: Malnutrition is a prevalent yet often overlooked phenomenon among orthopedic patients, and it can adversely affect postoperative recovery and functional outcomes. Aim: To explore the relationships between preoperative nutritional status and postoperative recovery, complications, functional and healthcare utilization in the postoperative patients undergoing major orthopedic surgery. Methods: The retrospective cohort study was conducted at a tertiary orthopedic center and included adults who underwent major orthopedic surgery from January 2017 through December 2023. Preoperative nutritional assessment was conducted using the Malnutrition Universal Screening Tool, Nutritional Risk Screening 2002, anthropometric measurements, and laboratory parameters. The patients were classified into malnourished and well-nourished. Independent-samples Results: Of 1,500 patients, 580 (38.7) were found to be malnourished. The older patients with malnutrition had a higher comorbidity and frailty score. They all exhibited a longer first ambulation time (44.6 vs. 29.4 h), less early mobilization (29.3% vs. 62.1%), a longer length of stay (10.9 vs. 7.0 days), and higher postoperative pain scores (all Conclusion: Preoperative malnutrition is significantly related to delayed recovery, more complications, worse functional outcomes, and increased healthcare use after orthopedic surgery. Timely nutritional screening and intervention could help enhance outcomes in the postoperative period.
