Endoscopists and endoscopic assistants’ qualifications, but not their biopsy rates, improve gastric precancerous lesions detection rate

Figure 3 Relationships between endoscopist biopsy rate, endoscopist qualifications and endoscopic detection. A: The relationship between endoscopist biopsy rate (EBR) and endoscopist qualifications is shown. The horizontal axis represents different groups of EBR (low, moderate, high/very high), and the vertical axis represents different groups of endoscopist qualifications (low, moderate, high/very high); B: The relationship between EBR and the positive detection rate is shown. The horizontal axis represents different EBR groups (low, moderate, high/very high), and the vertical axis represents endoscopic detection rates for different diseases (%). ρ: Spearman’s correlation coefficient. P < 0.05 indicates statistical significance. EBR: Endoscopist biopsy rate; GPCs: Gastric precancerous conditions; GPLs: Gastric precancerous lesions.
