The effect of infliximab on antiviral antibody profiles in patients with rheumatoid arthritis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The duration of humoral immunity in patients treated with immunosuppressive drugs is poorly defined. The objective of the study was to investigate the effect of infliximab on the levels of antiviral antibodies against poliomyelitis, rubella and measles in rheumatoid arthritis (RA) patients. Fifty-two consecutive RA patients being treated with 3 mg/kg infliximab were prospectively studied. The antiviral antibody profiles for measles, rubella and three serotypes of poliomyelitis were tested on the day of the first infusion of infliximab and 6 months later. The study group comprised 36 women and 16 men (mean age 54 years, range 33-81) with a mean disease duration of 15 +/- 9 years. Forty-two (81%) patients were being treated with methotrexate and 22 (42%) were receiving prednisone. All patients had baseline protective levels of antibodies against measles and the three strains of polio, while 48 (92%) patients had protective antibodies against rubella. No significant change in the levels of antiviral antibodies was observed after 6 months of treatment with infliximab: from 3.67 at baseline to 3.87 IU/ml for measles, 169.50-197.0 IU/ml for rubella. No change was noticed for the geometric mean concentrations of antibodies against strains of poliomyelitis: 366-478 IU/ml for the Mahoney polio strain, 906-845 IU/ml for the MEF strain and 175-196 IU/ml for the Sauket strain. Patients with longstanding RA conserve long-term immunity to common viruses despite the use of immunosuppressive drugs. Levels of antiviral antibodies against measles, rubella and polio remain stable under treatment with infliximab.
