This study was aimed to detect infection by ¹⁴C urea breath test and to describe the risk factors in asymptomatic adults at Kanbauk village-tract, located in Southern Myanmar. It was a community-based, cross-sectional prevalence study conducted between 4 and 9 October 2019. After thorough history taking, physical examination, obtaining informed consent, and fasting for 5 h, <i>H pylori</i> infection was detected by ¹⁴C urea breath testing. Among 149 volunteers, infection was detected in 68.46% of the study population. The prevalence of <i>H pylori</i> infection in male patients was 66.7% and in female patients was 75%. There was no statistically significant association between <i>H pylori</i> infection and gender (<i>P</i> = 0.36). The mean age of <i>H pylori</i> infected patients was 37.4 years (SD ± 9.14) and it did not differ significantly (<i>P</i> = 0.421).

Inclusion/exclusioncriteria were welldefined with a biasfree interpretation of complex statistical datasets; large sample size (N = 19 685 HCVpositive cases), a major study strength, added adequate statistical power (≥80%) reducing the possibility of potential selection bias in risk assessment amongst subgroups of HCVinfected persons: 4013 DAAtreated/3071 interferon (IFN)treated/12 601 untreated, with maximal 3 years’ clinical followup time. EHC risk was compared between treatment groups using Cox regression analyses, with adjustment for age/Charlson Comorbidity Index (CCI); matched case– control studyapproach wherein HCVinfected groups were stringently compared with matched cohorts without HCV from general Swedish population, reduced possibility of populationadmixture. Healthy/diseasefree, age/ethnicitymatched controls from random population significantly adds to statisticalpower of case– control association studies in “gastrohepatic diseaseweb”pathophysiology research2,3; Pandey has elegantly emphasized the significance of age/ethnicitymatched diseasefree controls from the general random population in multicentric epidemiology/ pharmacogenetics/genomics studies for demystifying the cellular/ molecular/genetic basis of inflammatory gastrohepatic ailments in susceptible cohorts.4 Overall, the findings of this study on HCVmediated EHC management in Swedish cohort(s) convincingly demonstrated that the HCVpositivity trend amongst 341 EHCs was appreciable: 84/43/214 EHC in DAA/IFN/untreatedgroup respectively; EHCrisk in DAAtreated compared with IFNtreated was doubled, but after adjustment for age/CCI, hazards ratio (HR) was 1.07 (95% CI 0.741.56). Cox regression analysis with controls revealed that EHCHR in DAAgroup = 1.45 (CI 1.131.86), with difference remaining statistically significant after adjusting for CCI. These findings may be successfully replicated in future multicentric large sample sizebased case– control prospective studies adhering to core tenets of good practice ethical research with longterm patient satisfaction trends.
