Effects of B-lymphocyte dysfunction on the serum copper, selenium and zinc levels of rheumatoid arthritis patients.
Article in Pakistan journal of medical sciences, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
objectiveTo study the effects of B-lymphocyte dysfunction on the serum copper, selenium and zinc levels of rheumatoid arthritis (RA) patients, and to provide evidence for clinical practice.
methodsSixty RA patients enrolled in our hospital from August 2009 to August 2013 were selected as the observation group. Another 60 healthy subjects who received physical examinations in our hospital were selected as the control group. Their B-lymphocyte stimulator (BlyS) levels and CD19(+)CD25(+) lymphocyte percentages were determined. The levels of trace elements were measured, and correlation analysis was performed.
resultsThe BlyS levels of the observation group and the control group were (0.39±0.21) ng/ml and (0.13±0.04) ng/ml respectively, which were significantly different (P<0.05). The percentages of CD25(+), CD19(+) and CD19(+)CD25(+) lymphocytes in the observation group were significantly higher than those in the control group (P<0.05). The serum copper, selenium and zinc levels of the observation group were significantly lower than those of the control group (P<0.05). Pearson's correlation analysis showed that the BlyS level was correlated with the levels of copper, selenium and zinc respectively (r=-0.541, -0.370, -0.430, P<0.05).
conclusionRheumatoid Arthritis may be induced by BlyS-mediated B-lymphocyte dysplasia and dysfunction, accompanied by decreased expressions of copper, selenium and zinc.
