However, sensitive analysis showed that the OR of the association between CD133 expression and histological type (ADC vs. SCC) in NSCLC patients was dramatically changed after removed one study (Alamgeer.M 2013) (OR = 1.13, 95% CI: 0.93–1.38, p = 0.3; I2 = 0%, p = 0.522) (Figure 5C). This evidence concerns the gene PROM1 and non-small cell lung carcinoma.
