Objectives
Narrative objectives1
Tuberculosis infection is a communicable disease caused by Mycobacterium tuberculosis, which spread from person to person through the air. Globally, an estimated 1.5 million people died out of 10 million tuberculosis (TB) cases. Well-established risk factors for TB infection includes human immunodeficiency virus infection, malnutrition, diabetes, alcohol abuse, use of immunosuppressive drugs, and exposure to tobacco smoke.
The ABO blood group was originally discovered for a safe blood transfusion in early 20th century. Each of two allele has antigen A, B, or null status. A combination of these alleles determines blood type of an individual (types A, B, AB, and O). Since its discovery, there has been an ongoing interest in the potential role of ABO blood groups in infectious disease. People with a specific blood group have an increased or decreased risk of some infectious diseases. For example, while a person with blood type O appeared to be more susceptible to norovirus infection, individuals who do not have blood type O are more susceptible to schistosomiasis. Individuals with B and AB blood group are reported less likely to be infected with H. pylori. Likewise, many researches have conducted to clarify how ABO blood groups affect the risk of tuberculosis. Nonetheless, we could not reach the conclusion because of discrepant result among studies.

Assessment
Primary outcomes
An ABO blood group with the lowest odds for tuberculosis will be selected as a common comparator. Then, odds ratio will be calculated for the other three blood groups using a network meta-analysis manner.

Study search
We will use the following search formulas.
Pubmed: ((abo [title] OR blood type [title] or blood group [title]) (tuberculosis or tb)) OR ((abo OR "blood type" or "blood group") (tuberculosis [title] or tb[title]))
Published
Int J Infect Dis. 2021 Mar;104:701-707.
Patients
We will divide Tuberculosis patients and controls into four ABO blood groups.
Analyses
The number of patients and controls will be compared between the two blood groups using the odds ratio (OR). If one or more cells in two-by-two contingency are null, 0.5 will be added to all cells.
The logarithm of OR and its standard error (SE) will be pooled using the frequentist weighted least squares approach random-model network meta-analysis using the "netmeta" command in "netmeta" package of R. A league table for OR accompanied with a 95% confidence interval (95% CI) will be presented.
A pairwise meta-analysis comparing two ABO blood groups using a group with the lowest odds for tuberculosis as a common comparator will also be conducted.
