The MPP group with a median age of 60 [29\u201389] months and the SPP group with a median age of 24 [10\u201340] months. Patients with MPP were older and had a higher occurrence of receiving antibiotics before admission, fever, dry cough, polypnea and diarrhea than patients with SPP (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2005&amp;lt;\u20050.01).

Laboratory findings in our study showed that there were significant differences between MPP and SPP patients in mean leucocyte count, neutrophil % (N%), lymphocyte % (L%), ALT levels, AST levels, LDH levels and incidence of accelerated procalcitonin (PCT) (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2005&amp;lt;\u20050.01). Lower age, no dry cough, no polypnea, lower LDH levels, and higher PCT might lead to the diagnosis of SPP. Our study showed that age had a higher accuracy in predicting MPP than LDH levels, with an age &amp;gt;48.5 months shown to be an independent predictive factor for the early evaluation and identification of MPP.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>In conclusion, patients with MPP and SPP usually present with fever, cough and some nonspecific symptoms.
