FIGURE 4: Meta-regression analysis depicting the relationship between dialysis duration (continuous, as measured in the paper), dialysis sessions (continuous, as measured in the paper), preterm, early preterm, very early preterm delivery and SGA. The circles represent the papers reporting on these outcomes, and their relationship is depicted by the regression line.
