The date from the initial diagnosis of periodontitis was characterized as the index date, and these periodontitis sufferers that were diagnosed with gastric HP have been excluded ahead of the index date. The comparison cohorts have been matched at a 1:1 frequency with the case group by age ( year span), gender, and history of visits to a hospital within 1 year from the index date, along with the similar exclusion criteria have been regarded for this group. In addition, both the periodontitis cohort along with the comparison cohort also excluded those who stopped utilizing the wellness insurance before entry into the study or these who have been younger than 20 years of age. 2.three. Study Outcome and Comorbidities The principal outcome of this study was the occurrence of gastric Hp (ICD-9-CM code 041.86). All participants had been followed-up with in the index date until Hp events occurred, they withdrew in the NHIRD program, death, or the finish of study period (31 December 2013). We identified numerous comorbidities related to ga.
