Correlations among clinical data
We examined the correlation coefficients (See Supplementary material, Figure S5) among these 26 clinical data and found that TBA was significant negative correlations with gestation days (r = -0.34), birth weight (r = -0.30), RDW.SD (r = -0.16), and significant positive correlations with TBIL (r = 0.52), DBIL (r = 0.56), IDBIL (r = 0.18), ALT (r = 0.17), AST (r = 0.18). And there was also a close relationship among liver function indexes. Such as, ALT highly positively correlated with AST (r = 0.93). ALT, AST positively correlated with TBIL, DBIL. TBIL positively correlated with DBIL (r = 0.89). Besides, CHOL, TG, LDL and uric acid also positively with ALT and AST. In addition, the concentration of Ca, Mg ion positively correlated with AST. The correlations between the above mentioned clinical data were significant (P < 0.05).
