PLOD1 and congenital rubella syndrome: Briefly, body weight gain was significantly decreased in the stressed rats compared with the corresponding controls in the CUMS (P < 0.001; Fig. 2a), CRS (P < 0.001; Fig. 2c), and SD (P < 0.01; Fig. 2d) models, but no statistical difference was found between the two groups in the LH model (Fig. 2b).
