CD68 and neoplasm: As shown in Table 2, the CD68+ TAMs density was not associated with age (older vs. younger: OR 0.83, 95% CI 0.56–1.24, P = 0.365), gender (male vs. female: OR 0.73, 95% CI 0.53–1.00, P = 0.051), tumor size (large vs. small: OR 1.27, 95% CI 0.89–1.80, P = 0.185), depth of invasion (T3–T4 vs. T1–T2: OR 1.54, 95% CI 0.90–2.63, P = 0.112), lymph node metastasis (present vs. absent: OR 1.67, 95% CI 0.92–3.03, P = 0.093), or Lauren type (diffuse vs. intestinal: OR 1.49, 95% CI 0.77–2.88, P = 0.232).
