  1. ERT = Enzyme Replacement Therapy; ADR = Adverse Drug Reaction, MedDRA = Medical Dictionary for Regulatory Activities; Q1 = 1st quartile; Q3 = 3rd quartile; SD = Standard Deviation
  2. Percentages were computed on patients belonging to the enrolled population who started the homecare setting before enrollment within each considered group; cohort A is consisting of Pompe disease patients receiving Myozyme in a homecare setting, while cohort B is composed of MPS I patients receiving Aldurazyme in a homecare setting.
  3. a Average duration of infusion was the time spent performing home infusions (hours) reported by patients for each performed dilution
  4. b Computed on the total number of prior ADRs occurred within each considered group; Each subject could have more than one prior Adverse Drug Reaction, but they are counted only once for each condition/row.
  5. c Terms were coded using MedDRA, version 24.0.
