The Impact of Body Mass Index on the Duration of Hospital Stay After Cardiac 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
backgroundThe impact of body mass index (BMI) on clinical outcomes after cardiac surgery remains controversial. The objective of this study was to evaluate the association between BMI and the duration of hospital stay in patients after cardiac surgery.
methodA retrospective, cross-sectional study was conducted with 1120 patients admitted to Beirut Cardiac Institute for cardiac surgery between July 2020 and July 2022. Patients were divided based on the BMI groups as follows: normal weight, overweight, obesity class I, obesity class II, and obesity class III. The length of hospital stay after cardiac surgery was compared among BMI groups after cardiac surgery, and also among each type of surgery.
resultsOf the 1120 patients who underwent cardiac surgery, 270 (24.1%) patients had normal BMI, 459 (41.0%) patients were overweight, and 391 (34.9%) patients were obese. The average length of hospital stay was 8.97 ± 5.88 days, with no correlation between BMI and length of hospital stay (r = 0.058; P = 0.052). Obesity class III patients experienced the longest stay (11.37 ± 7.09 days) with a significant difference compared to the length of hospital stay of normal weight patients (P = 0.007). Patients who underwent coronary artery bypass graft (CABG) surgery experienced the shortest duration of stay (8.50 ± 4.81 days) compared to the isolated valve surgery (9.46 ± 8.12 days) and combined CABG and valve surgery (10.52 ± 4.56 days; P ≤ 0.001). Within the CABG group, obesity class III patients had experienced the longest length of hospital stay (13.05 ± 8.85 days) with a significant difference compared to the length of hospital stay in normal weight patients (7.93 ± 3.11 days; P = 0.004).
conclusionOur results demonstrated no correlation between BMI and length of hospital stay after cardiac surgery. However, the obesity class III patients within the CABG group had the longest length of hospital stay. These findings highlight the importance of shifting the focus of healthcare planning to obesity class III, particularly in the context of specific surgical procedures.
