From: Cerebrospinal fluid in tuberculous meningitis exhibits only the L-enantiomer of lactic acid
Scatterplot showing the concentration of lactic acid in the CSF samples and the corresponding CSF glucose (values not reported in text) over different stages of TBM disease (dashed lines indicate respective reference ranges). Outcome severity: green circle = normal; yellow circle = mild neurological problems (e.g., learning difficulties, visual impairment); black circle = severe neurological problems (e.g., partial paralysis, severe motor impairment, cranial nerve palsy). *TBM stage: 1 = Glasgow coma score (GCS) 15 and no focal neurology; 2a = GCS 15 plus focal neurology; 2b = GCS 11–14 with focal neurology; 3 = GCS <11
