miR-29a-3p serves as a potential biomarker for diagnosing spinal tuberculosis: a comprehensive analysis integrating clinical data and molecular markers

miR-29a-3p shows distinct low expression in STB patients' peripheral blood, associated with inflammation activity and conventional diagnostic indicators, making it a promising auxiliary biomarker. Critically, integrating miR-29a-3p into combined detection strategies enhances and optimizes current STB diagnostic frameworks, addressing unmet clinical needs for more accurate and efficient diagnosis, thus holding substantial value for improving STB management.
