Data are also presented as mean (SD) for fat mass, lean mass, and BMI of the children with fractures caused by slight trauma compared with those without fractures and those with fractures caused by medium/severe trauma.
*
p values are for the difference between children with no fractures and those with fractures caused by slight trauma.
†
p values are for the difference between children with no fractures and those with fractures caused by moderate/severe trauma.
