Effect of time interval between therapy to vaccination on seroconversion rate. The studies were categorized into different subgroups based on time interval between HSCT and the vaccination, referring to the classification of the time interval in the original studies. The studies included in this figure contained individuals with one or two doses vaccines and were annotated in the figure. Two studies set 6 months as the cut-off (< 6 months and > 6 months) while three studies set 12 months as the cut-off (< 12 months and > 12 months). 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
