### 3.2. Construction of centiles

Centiles were calculated by the LMS method for total energy
expenditure expressed as kJ/d, kJ/kg per day and _{}

per day. The centile charts are shown in

**Figures 1
**to

**3**, respectively.

energy expenditure vs age derived from the LMS method, for a cohort of full-term
infants.

**Figure 2. **Centiles for total
energy expenditure vs age expressed on a per kg body weight basis.

**Figure 3. **Centiles for total
energy expenditure vs age expressed on a square root body weight
basis.
