Fig 3. Median and interquartile weight by age (on the centile scale) for DSH kittens in the underweight subset (blue) and overweight subset (red).

Plots are split by sex: (a) male and (b) female. On each graph, the median is depicted by the solid blue/red line, the interquartile range by the shaded region, and the standard centiles (0.4%, 2%, 9%, 25%, 50%, 75%, 91%, 98% and 99.6%), as calculated from the growth standard population, are shown by the grey horizontal lines (dotted, apart from 50%, which is shown as solid). Some centile crossing is observed in both groups up to 20-30wks but the overweight kittens continue to cross centiles throughout the growth period.
