Effects of CAP and DDP on OS cell viability. Three different human OS cell lines (MG63, 143B and HOS) were treated with various concentrations of CAP (a) and DDP (b) for 24 h, and cell viability was measured using a CCK-8 assay. Three OS cell lines, MG63 (c), 143B (d) and HOS (e), were exposed to various combinations of concentrations of CAP and DDP for 24 h, and cell viability was measured using a CCK-8 assay. The combination index (CI) of CAP and DDP was calculated for the three OS cell lines (f). The data are presented as the mean ± SD; *p < 0.05, **p < 0.01 and ***p < 0.001 compared with untreated cells
