Multivariate analysis for NBI-undetectable vs NBI-detectable lesions
| Factor | OR (95% CI) | P-value |
|---|---|---|
| Numerous irregularly shaped LVLs | 4.94 (1.39–17.5) | <0.05 |
| Position, anterior wall | 4.99 (1.58–15.8) | <0.05 |
| Synchronous SESCCs | 2.86 (0.85–9.60) | 0.09 |
| Macroscopic type, 0-IIba | – | – |
NBI, narrow-band imaging; OR, odds ratio; CI; confidence interval; LVLs, Lugol-voiding lesions; SESCC, superficial esophageal squamous cell carcinoma.

NBI-undetectable lesions were all 0-IIb and macroscopic type was omitted because of collinearity.
