Table 3.
Number of length/height, weight, and head circumference values from subjects by age groupa.
| Anthropometry | Age at last known contact | |||
|---|---|---|---|---|
| <10 years | ≥10 to 18 years | ≥18 years | Total | |
| Points/subjects | Points/subjects | Points/subjects | Points/subjects | |
| Length/height | 4,725/565 | 4,466/369 | 3,553/384 | 12,744/1,318 |
| Weight | 5,582/555 | 5,160/361 | 4,217/376 | 14,959/1,292 |
| Head circumference | 3,610/558 | 3,269/366 | 2,434/315 | 9,313/1,239 |
| Total | 13,917/579 | 12,895/374 | 10,204/412 | 37,016/1,365 |
In the youngest age category (<10 years), there were 579 subjects (42.1%) of the primary achondroplasia cohort (PAC) who contributed a total of 13,917 anthropometric values. There were 374 (27.2%) individuals of the PAC contributing 12,895 anthropometry values from 10 years of age up to 18 years, and 10,204 data points from 412 (30.0%) individuals 18 years of age and older.
aNine PAC members were excluded from this table (and growth curves). Five subjects were preterm and had anthropometry available only from the first 2 years of life and four had anthropometry available only after undergoing limb lengthening, growth hormone treatment, or clinical trial participation.
