Table 5.
This table is an additive stepwise regression model, which begins by including the covariates from Tables 3 and 4 (age, gender, socio-economic status (SES) score and weight-for-age z score (WAZ: Epi Info CDC 2000). These are followed by the cerebral malaria with positive retinopathy (CM-R) clinical measures of HIV status (positive, negative), a reported history of seizures prior to CM illness (History seizures: yes, no), occurrence of observed seizures at admission or during hospitalization (Seizures in hospital: yes, no), confirmed epilepsy 1 year after illness (Epilepsy after illness: yes, no), duration of coma following admission (h), blood haematocrit level at admission (%), serum platelet counts at admission (µl) and serum lactate level at admission (absolute). The predicted outcome measures are the Malawi Developmental Assessment Tool (MDAT) domain scores (Gross Motor, Fine Motor, Language, Social Skills), MDAT total score and Child Behaviour Checklist (CBCL) Internalizing and Externalizing Symptoms total. The stepwise regression stops when all remaining variables have P-values >0.15. Empty cells indicate that the enter P-value was >0.15. Only the CM-R group is included in this table. Total percentage of explained variance for that outcome measure (R2) is in the bottom row of the table
