1 · What the graph read from 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.

2 · The registry

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

BACKGROUND/

objectivesThe purpose of this study was to investigate whether vitamin B(6) supplementation had a beneficial effect on inflammatory and immune responses in patients with rheumatoid arthritis (RA). SUBJECTS/

methodsThis was a single-blind co-intervention study performed at the Division of Allergy, Immunology and Rheumatology of Chung Shan Medical University Hospital, Taiwan. Patients were diagnosed with RA according to the 1991 American College of Rheumatology criteria for RA. Patients were randomly allocated into two groups: control (5 mg/day folic acid only; n=15) or vitamin B(6) (5 mg/day folic acid plus 100 mg/day vitamin B(6); n=20) for 12 weeks. Plasma pyridoxal 5'-phosphate (PLP), serum folate, inflammatory parameters (that is, high-sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha)) and immune parameters (that is, white blood cell, total lymphocyte, T-cell (CD3), B-cell (CD19), T-helper cell (CD4), T-suppressor (CD8)) were measured on day 1 (week 0) and after 12 weeks (week 12) of the intervention.

resultsIn the group receiving vitamin B(6), plasma IL-6 and TNF-alpha levels significantly decreased at week 12. There were no significant changes with respect to immune responses in both groups except for the percentage of total lymphocytes in the vitamin B(6) group when compared with week 0 and week 12. Plasma IL-6 level remained significantly inversely related to plasma PLP after adjusting for confounders (beta=-0.01, P=0.01).

conclusionsA large dose of vitamin B(6) supplementation (100 mg/day) suppressed pro-inflammatory cytokines (that is, IL-6 and TNF-alpha) in patients with RA.
