Epstein-Barr virus in peripheral blood is associated with response to rituximab therapy in rheumatoid arthritis patients.

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
Autoreactive B cells infected by Epstein-Barr virus (EBV) are suspected to be involved in the etiology of various human chronic autoimmune diseases. This motivated us to study the relationship between peripheral blood EBV load at baseline and treatment response to B cell-depleting therapy in rheumatoid arthritis (RA) patients. Thirty-five RA patients who started treatment with rituximab (RTX) in a routine clinical setting were assessed for baseline disease activity using disease activity score using 28 joint counts (DAS28) (erythrocyte sedimentation rate [ESR]). Treatment response was evaluated 3-7 months after RTX. EBV load in baseline whole blood (WB) samples was determined using quantitative PCR. EBV DNA was detected in 16/35 (46 %) of the WB samples. In these 16 EBV-positive patients, the median viral load was 3.15 (2.68-4.00) log copies/ml. Good/moderate European League Against Rheumatism (EULAR) response was observed in 16/16 of the EBV DNA-positive vs 13/19 EBV DNA-negative patients, p = 0.022. Significant response (DAS28 change >1.2) was observed in 14/16 of the EBV DNA-positive vs 10/19 EBV DNA-negative patients, p = 0.035. The decline in DAS28 after RTX was 2.10 (1.03-4. 78) in the EBV DNA-positive vs 1.47 (-0.7-4.70) in the EBV DNA-negative patients, p = 0.13. EBV load at baseline significantly correlated with change in DAS28 after RTX (τB = -0.261, p = 0.042). Our results suggest that the presence of EBV genome in WB could serve as a predictive marker to RTX therapy in RA.
