Longitudinal characteristics of the anthropometry data for 1,341 subjects with achondroplasia

	Length/height N (% of total population)	Weight N (% of total population)	Head circumference N (% of total population)
> 3 points	977 (71.1)	968 (70.5)	879 (64.0)
> 5 points	799 (58.2)	823 (60.0)	699 (50.9)
≥ 10 points	510 (37.1)	544 (39.6)	385 (28.0)

The majority of the anthropometry data were longitudinal in nature with over 500 subjects contributing 10 or more length/height and weight values and nearly 400 with 10 or more head circumference values
