Halimeter scores among individuals with different genotypes before and after intervention. A The schematic diagram of the prospective study. B Halimeter scores in halitosis patients with different genotypes at baseline and 1-, 3-, and 6-month after intervention. Data were presented as mean ± SD. ***, P < 0.001 as compared to the baseline. $$$, P < 0.001 as compared to non-AVI/AVI genotype at the same time point after treatment. C-D The changes of halimeter scores in non-AVI/AVI (C) and AVI/AVI (D) groups at 1, 3, and 6 months after treatment. The data are represented as individual symbols, and statistical analysis was conducted using paired samples t-tests. ***, P < 0.001
