Methodological comparison of capillary and venous blood parameters in pediatric Mycoplasma pneumoniae pneumonia: a prospective study with exploratory machine learning assessment

Routine blood testing is one of the most common tests for patients. However, the clinical value of many parameters remains to be further explored. The aim of this study was to evaluate the differences in routine blood parameters between capillary blood (CB) and venous blood (VB), and to explore their clinical application in stratifying the severity of Mycoplasma pneumoniae pneumonia (MPP).
