Comparison of seropositive rates between patients receiving HSCT or CAR T-cell therapy and healthy controls. The comparison of seropositive rates between HSCT or CAR T-cell recipients and healthy controls after one dose (A), two doses (B) or three doses (C) of COVID-19 vaccine were plotted. The solid circles indicates the odds ratio, and the horizontal lines mean the 95% CIs. The diamonds indicate the pooled estimate, and the lateral tips of the diamonds mean the 95% CIs. The event rate, lower limit, upper limit and relative weight were analyzed using the random effects models. The heterogenicity of each subgroup was represented by Q, I² and P values as described in Methods
