| Definition | This parameter is part of a confidence model for AMR developed by the Relational Sequencing Tuberculosis Data platform (ReSeqTB, https://platform.reseqtb.org). The confidence model is based on the likelihood ratio test (LR+) statistic that is used to evaluate whether mutations are positively or negatively associated with phenotypic resistance. The LR+ is derived from a drug susceptibility test, testing sensitivity and specificity. Under the null hypothesis of no association, the LR value is expected to be 1, but deviations from this can be due to an association with resistance or a low number of available isolate samples. The LR+ measures the strength of association between the presence of a mutation and the drug resistance phenotype. A mutation graded as minimal confidence has a minimal association of the mutation with phenotypic drug resistance. There is inconclusive evidence that the mutation confers or is strongly associated with drug resistance. LR value is greater than 1 but less or equal to 5. |
