Correlations (r value) between CRP, ALT, Anti-MP IgM and blood coagulation indexes.

Indexes	PT (s)	P	APTT (s)	P	FIB (g/L)	P	TT (s)	P	D-D (mg/L)	P
CRP (mg/L, in all cases)	0.245	.014	−0.103	.305	0.355	<.001	−0.223	.025	0.150	.134
CRP (mg/L, in all subjects)	0.186	.006	−0.118	.080	0.390	< .001	−0.074	.275	0.226	.001
ALT (U/L, in all cases)	−0.054	.595	−0.203	.043	0.070	.491	−0.103	.307	0.602	<.001
ALT (U/L, in all subjects)	−0.013	.849	−0.123	.069	−0.020	.766	−0.013	.847	0.399	< .001
Anti-MP IgM (U/mL, in all cases)	−0.048	.634	−0.221	.027	−0.072	.475	0.107	.288	−0.001	.994

All subjects refer to all cases (children with mycoplasma pneumoniae pneumonia) and controls; ALT = alanine transaminase, APTT = activated partial thromboplastin time, CRP = C-reactive protein, D-D = D-dimer, FIB = plasma fibrinogen, PT = prothrombin time, TT = thrombin time.
