[Statistico-mathematical appraisal of the length of the pretherapeutic interval in the prognosis of tubercular meningitis in children].

The data obtained concerning the two main parameters for the prognosis of tuberculous meningitis: onset-admission interval, assessed anamnestically and electtoencephalogram performed on admission, were processed mathematically by computer. The EEG is a more reliable parameter for assessing the gravity of the lesions on admission that the anammestic data regarding the onset, at a signficance threshold of 10.48% as against 5.23%. For 11.3 days there was a close correspondence between the two parameters, after which the onset-admission variable became aleatory, the only objective index of gravity being the EEG. Statistico-mathematical processing increases the objectivity and precision of the prognosis.
