Results
This study enrolled 60 children with short stature from 28 Japanese medical institutions and analyzed 57 of them. The median and mean adherence rates after 24 wk of observation were 96% and 93%, respectively. Although adherence rates were significantly lower from wk 16 to wk 20 than from wk 1 to wk 4, cumulative adherence rates remained high throughout the observation period. The questionnaire analysis revealed that most patients actively used the application.

Baseline Characteristics
The mean age (SD) of the patients was 7.2 (3.84) yr, and the proportions of male and female patients was almost similar. A total of 54.4%, 7.0%, and 38.6% of the included patients were diagnosed with GHD, TS, and SGA, respectively. A relatively high proportion of patients were diagnosed with SGA. Among all patients, patients with SGA started GH therapy at the lowest age (P = 0.002). The baseline mean (SD) height SD score was -2.71 (0.57).
Participant flow
This study enrolled 60 patients with short stature from 28 Japanese medical institutions. Three patients discontinued shortly after GH therapy initiation due to medication change, unbearable pain, and failure to return to the hospital and were subsequently excluded from the statistical analysis.

Outcome measures
Good adherence rates to GH therapy were observed with the use of the treatment-supporting application. Analyses of questionnaire answers revealed that most patients actively used the application.
