Fig 5. Catch-up growth occurs in the IUGR offsprings.
A. Body weights of the controls (CTL) and the IUGR offsprings were recorded at birth (day 0), 2, 7, 14 and 21 days, as well as 2 and 4 months of age. Data are shown as mean ± SD. n = 45; *p < 0.05 vs. CTL. B. Based on the mean and standard deviations of body weights, IUGR offsprings were further identified as with catch-up growth (CG-IUGR), with over catch-up growth (OCG-IUGR), and without catch-up growth (W/O CG-IUGR). Data are shown as mean ± SD. n = 45 (CTL), 15 (W/O CG-IUGR), 18 (CG-IUGR), and 12 (OCG-IUGR); *p < 0.05 vs. CTL. C. The fractional growth rate was plotted from day 2 to 4 months for the controls, W/O CG-IUGR, CG-IUGR and OCG-IUGR. Data are shown as mean ± SD. n = 45 (CTL), 15 (W/O CG-IUGR), 18 (CG-IUGR), and 12 (OCG-IUGR); *p < 0.05 vs. CTL. D. The fractional growth rate was plotted from day 2 to 4 months for the controls and the whole IUGR offsprings. Data are shown as mean ± SD. n = 45; *p < 0.05 vs. CTL.
