National Cooperative Growth Study (NCGS): A Post-marketing Surveillance Program for Nutropin, Nutropin AQ, Nutropin Depot, and Protropin

Study Overview
=================
Brief Summary
-----------------
The purpose of this multicenter, open-label, observational, post-marketing surveillance study is to collect long term safety and efficacy information on growth hormone (GH) products: Protropin (somatrem for injection), Nutropin (somatropin for injection), Nutropin AQ (somatropin for injection), and Nutropin Depot (somatropin for injectable suspension) in the treatment of pediatric growth disorders for which GH is prescribed.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Who Died |  | From October 1985 to June 2010 (overall approximately 24 years and 9 months) | 
| First Year Annualized Growth Rate | Annualized growth rates are expressed as centimeters per year (cm/yr), computed as the change in height (centimeters) divided by the change in age (years). Growth rates were calculated from the date of the first injection (baseline/ enrollment) to the visit closest to 365*1 days after baseline. Visits within 90 days of 365*1 days after baseline may be used. If multiple visits within 90 days were reported then the visit closest to 365*1 days was used. Growth rates less than (<) -1 or greater than (>) 30 cm/yr were excluded. Growth rates from -1 to 0 were set to 0 cm/yr. Growth rates are summarized by etiology group and gender. Only those participants who had non-missing 1-year growth rate data were included in the analysis. | Year 1 | 
| Second Year Annualized Growth Rate | Annualized growth rates are expressed as cm/yr, computed as the change in height (centimeters) divided by the change in age (years). Growth rates were calculated from the date of the visit closest to 365 days after baseline to the visit closest to 730 days. Visits within 90 days of 365 and 730 days after baseline may be used. If multiple visits within 90 days were reported then the visit closest to 365 or 730 days was used. Growth rates <-1 or >30 cm/yr were excluded. Growth rates from -1 to 0 were set to 0 cm/yr. Growth rates are summarized by etiology group and gender. Only those participants who had non-missing second-year growth rate data were included in the analysis. | Year 2 | 
| Third Year Annualized Growth Rate | Annualized growth rates are expressed as cm/yr, computed as the change in height (centimeters) divided by the change in age (years). Growth rates were calculated from the date of the visit closest to 730 days after baseline to the visit closest to 1095 days. Visits within 90 days of 730 and 1095 days after baseline may be used. If multiple visits within 90 days were reported then the visit closest to 730 or 1095 days was used. Growth rates <-1 or >30 cm/yr were excluded. Growth rates from -1 to 0 were set to 0 cm/yr. Growth rates are summarized by etiology group and gender. Only those participants who had non-missing third-year growth rate data were included in the analysis. | Year 3 | 
| Near Adult Height (NAH) | Heights were standardized with height standardized deviation scores (SDS) to enable height comparisons across ages and sexes using methods and height standards found at: http://www.cdc.gov/growthcharts/cdc_charts.htm. NAH were calculated overall and by etiology groups for participants who had both a non-missing value available height z-score and a non-missing enrollment height (EH) SDS, as well as for participants with 3 or more years of GH therapy (GHT ≥3y). | From October 1985 to June 2010 (overall approximately 24 years and 9 months) |
