Preoperative Ultrasonographic Assessment of the Gastric Antrum in Diabetic Patients Before Elective Surgery: A Prospective Observational Comparative Cohort 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
backgroundDiabetic patients may have neuropathy-induced gastroparesis predisposing them to aspiration. Point-of-care gastric ultrasonography (GUSG) is useful in the qualitative assessment of the antrum and quantitative prediction of gastric volume (GV) in diabetic patients. In this study, we compared the GUSG findings between fasting diabetic and non-diabetic patients in the elective preoperative setting.
methodsA total of 220 patients were included in the study with 110 diabetic patients in the diabetes mellitus (DM) group and 110 non-diabetic patients in the non-diabetes mellitus (NDM) group. GUSG was performed in supine and right lateral decubitus (RLD) positions and qualitative grading was done. An empty antrum in both supine and RLD positions was graded 0. Fluid present in the RLD position but empty in the supine position was graded 1. The presence of solids or fluid in both supine and RLD positions was graded 2. Quantitative assessment was done by calculating the estimated GV using the measured cross-sectional area (CSA). The presence of grade 2 antrum or solids or GV >0.8 mL/kg was considered as criteria for a 'high-risk' antrum.
resultsGrade 2 antrum was found in 18% of patients in the diabetic group compared to 3% in the non-diabetic group. Mean CSA (5.65 cm
conclusionDiabetic patients have a higher incidence of grade 2 antrum, and higher CSA and GV, when compared to non-diabetic patients. Risk factors such as female gender and increasing age are associated with the high-risk antrum incidence. Further studies where objective tests are done to identify the presence of diabetic autonomic neuropathy might help determine the relationship between GUSG and aspiration risk.
