Table 4. Comparison between FI and NEC groups, in changes of CBC at three time points (n=92).
1 Comparison was done using the independent t-test. 2 Comparison was done using the Mann-Whitney test
All data are expressed as mean ±SD except as indicated. * per microlit, ** x 109 per lit, *** gm per dL
CBC = Complete blood count; Hb = Hemoglobin; FI = Feeding intolerance; IQR = Interquartile range; NEC = Necrotizing enterocolitis; WBC = White blood count
