A Pilot Study on the Diagnostic Accuracy of Proadrenomedullin and Proatrial Natriuretic Peptide in Lower Respiratory Tract Infections

Fig. (1) Box plots of the MR-proANP plasma levels in the study population. The patients with pneumonia had similar MR-proANP levels (median 233 pmol/L [IQR 25-75, 115-398 pmol/L]) compared with those with other LRTIs (median 259 pmol/L [110-399 pmol/L]) (p=0.88). The Box plots represent the 25^th and 75^th percentiles, with the internal horizontal lines showing the median. T-shaped bars represent the 10^th and 90^th percentiles. IQR, interquartile range; MR-proANP, mid-regional proatrial natriuretic peptide.
