marginally significantp = 0.113
The results showed that measured fluid balance has a marginally significant correlation with weight changes (r = 0.195; p = 0.113), indicating that the accuracy of the measured fluid balance in our study was barely satisfactory. 3.3 Associations between Fluid-Related Factors and Treatment Outcome According to univariate analysis, fluid balance before FIT was slightly significantly lower in infants successfully responding to FIT compared to those with failed closure of hsPDA [31.82 (18.01, 39.66) vs 34.68 (25.31, 43.56); p = 0.049; Table 3 , Fig. 2 A].
