Document Type : Systematic Review and Meta-analysis


Department of Epidemiology and Biostatistics, Faculty of Public Health, Khon Kean University, 40002, Thailand.


Objective: To investigate the accuracy of OC-Sensor and colorectal cancer screening in a population-based randomized controlled trial at Khon Kaen province, Thailand. Methods: The MOOSE Guidelines for Systematic Reviews and Meta-Analyses of Observational Studies was applied. Eligibility criteria were English language, hand searching was conducted using Medline databases from 2010 to 2021 for identify literatures reviews of OC-Sensor and colorectal cancer screening. The initials screen based on the research titles and abstracts, final screenings based on full-text reports. Synthesis the results with meta-analysis using fixed effect model, random effect model, determined statistically significant with p-value < 0.05.  Confirmed the pooled effect sizes of high heterogeneity by meta-regression including tested precision of each estimates by bubble plot using STATA version 14. Results: Meta-regression showed sensitivity of OC- sensor = 72.54% (95% CI: 65.82-79.25), and specificity of OC- sensor = 89.59% (95% CI: 87.23-91.95). Conclusions: Sample size and cut-off of fecal hemoglobin concentration in each study were differed but sub-group analysis and sensitivity analysis were not considered for this analysis because population, setting and location for detected cancer of included study are not differences.
