Figure 1.

Median, mainimum, maximum and corresponding inter-quartile (25 and 75th centile) range for 25(OH)D, osteocalcin, and CTx-I in middle adolescent (n = 12) and late adolescent to early adulthood (n = 14) female basketball players. In the box plots, whiskers indicate the minimum and maximum values, the boundary of the box closest to zero indicates the 25th percentile, a black line within the box marks the median, and the boundary of the box farthest from zero indicates the 75th percentile.
