Forest plot of impacts of adjuvant TACE on OS and tumor recurrence in subgroup patients after IPTW analysis. Squares represent point estimates for the hazard ratio as compared with non-TACE, and horizontal lines indicate the associated 95% CIs. Hazard ratios and P values were estimated with the use of propensity-weighted Cox proportional-hazards models. OS, overall survival; TTR, time to recurrence; IPTW, inverse probability of treatment weighting; TACE, transarterial chemoembolization.
