Independent predictors for poor prognosis of TBM (conditional logistic regression model)a
| Independent predictor | OR | 95% CI | P valueb |
|---|---|---|---|
| Age (yr) | 1.040 | 0.953-1.134 | 0.3803 (NSD) |
| Culture for M. tuberculosis | 37.368 | 1.233-1132.781 | 0.0375 |
| Single-PCR assay | 0.069 | 0.001-3.236 | 0.1731 (NSD) |
| Nested-PCR assay | 6.125 | 0.489-76.770 | 0.1600 (NSD) |
| M. tuberculosis DNA copy no. of >8,000 (WR-QNRT-PCR assay) | 16.142 | 1.191-218.79 | 0.0365 |
| More than 2 wk to initial sample collection | 32.501 | 1.709-618.21 | 0.0205 |
a
The association of the specifically diagnostic parameters with risk for the poor prognosis for TBM (death) was tested using conditional logistic regression analysis. A backwards elimination procedure was used for multivariable analysis. For multivariate risk predictors, the adjusted OR values are given with the 95% CI values.
b
NSD, no significant difference.
