Error between the ODE model output and cell culture and VEGF concentration data.

All errors are relative errors between the model output and experimental data. The dashes (-) denote where the data is not available to calculate the quantity, and the asterisk (*) denotes when the data records a value of less than 2% of the baseline concentration of 1100 pg/mL, thereby precluding computing the relative error (i.e., it would be near infinite).所有误差均为模型输出与实验数据之间的相对误差。破折号（-）用于表示无法获取该指标计算所需的数据；星号（*）则表示该数据记录的数值低于基线浓度1100 pg/mL的2%，因此无法计算相对误差（此时相对误差将趋近于无穷大）。
