Relationship between neonatal respiratory distress syndrome pulmonary ultrasonography and respiratory distress score, oxygenation index, and chest radiography grading

Figure 6 Scatter plot of the relationship between the respiratory distress syndrome neonatal ultrasonography score, respiratory distress score, oxygenation index, and chest X-ray grade before and after treatment. A: Relationship between the pretreatment ultrasonography scores and respiratory distress scores; B: Relationship between the pretreatment ultrasonography score and oxygenation index; C: Relationship between the pretreatment ultrasonography scores and chest X-ray grade; D: Relationship between the ultrasonography scores and respiratory distress scores after treatment; E: Relationship between the ultrasonography scores and oxygenation index after treatment; F: Relationship between the post-treatment ultrasonography score and chest X-ray grade; the red circle in the figure represents the corresponding data of each sample indicator.
