Current status of artificial intelligence colonoscopy on improving adenoma detection rate based on systematic review of multiple metanalysis

Table 4 Subgroup analysis of factors affecting adenoma detection rate in artificial intelligence colonoscopy

Ref.	ADR based on endoscopist		Indication for colonoscopy
	Baseline ADR < 25%	Baseline ADR ≥ 40%	Screening	Surveillance
Soleymanjahi et al[25]	RR: 1.39, 95%CI: 1.18-1.63. Similar improvements in ADR, but data were less stratified	RR: 1.14, 95%CI: 1.08-1.21. (> 1000 colonoscopies): ADR improved by 19%. (RR: 1.19, 95%CI: 1.11–1.27, P < 0.001, I2 = 24.51%)	Significant improvement. RR: 1.21, 95%CI: 1.15-1.28, I2 = 76%	Less improvement. RR: 1.14, 95%CI: 1.05-1.24, I2 = 65%
Makar et al[17]	Improvement. RR: 1.23, 95%CI: 1.16–1.32, I2 = 0%, P < 0.001	Improvement. RR: 1.24, 95%CI: 1.15–1.34, I2 = 45%, P < 0.001	Improvement. RR: 1.13, 95%CI: 1.07–1.19, I2 = 15%, P < 0.001	Improvement. RR: 1.33, 95%CI: 1.23–1.45, I2 = 42%, P < 0.001
Lee et al[15]	No significant improvement. RR: 1.01, 95%CI: 0.84–1.20		16% increase in ADR compared to standard colonoscopy, but the result was not statistically significant. RR for ADR: 1.16, 95%CI: 0.83–1.62, I2 = 77%	5% increase in ADR but the result was not statistically significant. RR for ADR: 1.05, 95%CI: 0.92–1.19, I2 = 62%
Lou et al[18]	Significant improvement. RR: 1.42, 95%CI: 1.28–1.58, I2 = 65%	Minimal improvement. RR: 1.12, 95%CI: 1.03–1.22, I2 = 52%
Deliwala et al[40]	Significantly improved. AUC: 0.97, 95%CI: 0.96–0.98, P < 0.01	Moderate improved. AUC: 0.90, 95%CI: 0.87–0.93, P < 0.01

RR: Relative risk; OR: Odd ration; AUC: Area under curve; ADR: Adenoma detection rate.
