Randomized controlled trials comparing both strategies were included. Outcomes were hypoglycaemia, aspiration pneumonia, contrast-induced acute kidney injury (AKI), nausea\/vomiting, hypotension, and patient satisfaction. Risk of bias was assessed using the RoB 2.0 tool. All meta-analyses were performed using a random-effects model. Six studies were included (n = 2736). The mean age ranged from 62 to 70 years, and 31% were female. There was no significant difference in the risk of hypoglycaemia [risk ratio (RR) 0.82, 95% confidence interval (CI) 0.49\u20131.38], aspiration pneumonia (RR 1.31, 95% CI 0.28\u20136.05), nausea\/vomiting (RR 0.95, 95% CI 0.58\u20131.55), contrast-induced AKI (RR 1.87, 95% CI 0.94\u20133.72) between the non-fasting and fasting groups. In contrast, patients in the non-fasting group had a lower risk of hypotension (RR 0.57, 95% CI 0.38\u20130.86) and higher satisfaction scores (standardized mean difference \u22121.53, 95% CI \u22122.11 to \u22120.96) compared with the fasting group. The risk of bias was judged as some concerns in three of four studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
