The pneumococcal antibody assay was a fluoroimmunoassay that used a Luminex Multiplex platform. Purified capsular polysaccharides isolated from 12 serotypes of S. pneumonia were covalently attached to microbeads and used as a capturing reagent. Phycoerythrin conjugated anti-human IgG was used for detection. A positive immune response against a serotype was defined as a 2-fold increase or an increase of \\> 1 μg/mL from pre-vaccination levels.","groups":[{"description":"Patients received 2 intravenous infusions of rituximab 1000 mg, 14 days apart + methotrexate 10-25 mg/wk orally or subcutaneously during the Treatment Period.","id":"OG000","title":"Rituximab + Methotrexate (Group A)"},{"description":"Patients received methotrexate 10-25 mg/wk orally or subcutaneously during the Treatment Period.","id":"OG001","title":"Methotrexate (Group B)"}],"paramType":"NUMBER","populationDescription":"Immune response per-protocol population: Group A - All patients randomized to Group A who received any rituximab infusion and any vaccine and had pre-vaccination and 4-week post-vaccination blood samples.
