  1. Keys: CHM, Chinese herbal medicine; CI confidence interval; CRC, colorectal cancer; FOLFOX, the FOLFOX regimen refers to 5–Fluorouracil + Leucovorin combined with Oxaliplatin; KLT, Kanglaite injection; NA, not applicable; NSCLC, non-small lung cell cancer; NP, Cisplatin + Vinorelbine; NR, not reported; OR, odds ratio; RR, relative risk; SFI, Shenqi Fuzheng injection; TACE, Transcatheter arterial chemoembolization.
  2. #All chemotherapy toxicities were measured with the World Health Organization toxicity criteria;
  3. *p < 0.05 for the heterogeneity test;
  4. ^CHM denotes the inclusion of all types of Chinese herbal medicines. The use of generic terms “chemotherapy” or “radiotherapy” denote that the specific treatments used were not described in the original meta-analyses publications.
  5. Effects on dichotomous data were summarized with risk ratio (RR) or odds ratio (OR) to measure the risk of experiencing certain outcome in the treatment group as compared to the control group.
