Comparison of prediction error and absolute prediction error using SRK II and BU II formulae in the age group

Groups	PE_SRK II	APE_SRK II	PE_BU II	APE_BU II
≤2 years n=23	−0.15±0.84	0.67±0.50	−0.07±1.71	1.20±1.19
3-5 years n=30	−0.99±1.29	1.32±0.94	0.1±1.51	1±1.11
5-8 years n=19	−0.54±0.9	0.76±0.71	0.09±0.74	0.56±0.47
P	0.02	0.017	0.311	0.104

PE: Prediction error; APE: Absolute prediction error. The values of PE and APE are expressed as mean±standard deviation
