Forest plots of ORR stratified by drug class. ORR between cytotoxic chemotherapy and epigenetic modifiers in patients with R/R PTCL-NOS (A), ORR between cytotoxic chemotherapy and epigenetic modifiers in patients with R/R AITL (B), ORR between cytotoxic chemotherapy and SMis in patients with R/R PTCL-NOS (C), and ORR between cytotoxic chemotherapy and SMis in patients with R/R AITL (D). Forest plots are arranged in alphabetical order by author’s last name. Squares represent estimated proportions, with the size of the squares representing the weight of each trial according to the inverse variance method. Horizontal lines through the squares indicate 95% CIs. The points of the diamond indicate the 95% CI of the pooled mean. Horizontal line at the bottom indicates the prediction interval. Blank lines indicate missing information from the trial manuscript.
