The authors regret that there was a typo in Eq. (8) and that yLOEWE should be yc. The corrected equation is:
(8) |
Eq. (8) was used for introducing the concept of the Combination Index (CI). Calculation of CI used the R package SYNERGY which was based on the correct equation as above and therefore this typo won't affect any results and conclusions in the paper. The authors would like to apologise for any inconvenience caused.
