After examining the clinical efficacy of all SNPs of CX3CL1/CX3CR1 on carboplatin-treated ovarian cancer patients, we comprehensively evaluated the effect of demographic factors, clinical indicators and SNPs on carboplatin-treated ovarian cancer patients by the Mann–Whitney U test and χ2 test, and the results are shown in Table 4. This evidence concerns the gene CX3CL1 and ovarian cancer.
