Data were compared using Mann-Whitney test (ease of SCIg training, number of SCIg training sessions) or Fisher’s exact test (SCIg training location, type of SCIg trainer). Significant p values are in bold

PFS pre-filled syringes, SCIg subcutaneous immunoglobulin

^aOther training locations: Institut de recherches cliniques de Montréal (vials, n=1; PFS, n=3) or a local community service center (vials, n=0; PFS, n=1)

^bOther concerns: applying needles to tubing (vials, n=0; PFS, n=1)
