Table 2. Diagnostic parameters of Minim typing for CC8 and subCCs within CC8.
CC/subCC | STsa | MelTsb | Sensitivity | Specificity | PPV | |||
Rawc | Enhancedd | Raw | Enhanced | Raw | Enhanced | |||
8 (all) | 185 | 22 | 0.973 | 0.965 | 0.976 | 0.983 | 0.863 | 0.906 |
8–8 | 110 | 10 | 0.891 | 0.935 | 0.992 | 0.998 | 0.899 | 0.972 |
8–239 | 44 | 7 | 0.911 | 0.948 | 0.992 | 0.997 | 0.788 | 0.932 |
8–72 | 14 | 1 | 0.717 | 0.733 | 0.996 | 0.996 | 0.630 | 0.688 |
8–247 | 11 | 0e | ND | ND | ND | ND | ND | ND |
8–770 | 6 | 2 | 0.830 | 0.897 | 0.997 | 0.997 | 0.560 | 0.625 |
The calculations assumed equal abundance of all STs. ND = not determined.
Number of STs belonging to the CC/subCC.
Number of MelTs diagnostic for the CC/subCC. Each MelT defines either a single ST belonging to the CC/subCC of interest, or a group of STs of which at least 50% are of the CC/subCC of interest.
The CC and subCC assignments for STs in the Excel key were used without modification.
Singletons that are DLVs of the founder of the CC/subCC were classified as true positives, and false positive and false negative STs that are SLVs for more than one CC/subCC founder were assigned to the CC/subCC that maximizes the diagnostic parameters. Additional singletons that are founder DLVs and do not correspond to MelT diagnostic for the CC/subCC of interest were identified as new false negatives.
There are no MelTs diagnostic for subCC 8–247 according to the criterion used, primarily because CC7 and subCC 8–247 are not discriminated by Minim typing.
