Last Updated: 2012-05-22

Results Overview

Participants were asked the following question from Section II of the Injection Pen Assessment Questionnaire (IPAQ) patient-reported outcome (PRO) tool, "Thinking about the Genotropin pen and the new injection pen you used over the past few months, please compare both injection pens and choose which one is easier to use overall?" Choices included: Genotropin Pen® easier to use, new injection pen easier to use, or no difference.

Measure	Mark VII Pen Then Genotropin® Pen Participant (not caregiver) used Mark VII pen (subcutaneous injections daily for 2 months) then the current Genotropin® pen (subcutaneous injections daily for 2 months). Both pens provided in 5, 5.3, and 12 mg doses of Genotropin (somatropin recombinant deoxyribonucleic acid \[rDNA\] origin); doses received by participants based on body weight.	Genotropin® Pen Then Mark VII Pen Participant (not caregiver) used current Genotropin® pen (subcutaneous injections daily for 2 months) then the Mark VII pen (subcutaneous injections daily 2 months). Both pens provided in 5, 5.3, and 12 mg doses of Genotropin (somatropin \[rDNA origin\]); doses received by participants based on body weight.
