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 &

objectivesInterleukin-1 (IL-1) is one of the pro-inflammatory cytokines that plays a main role in the regulation of immune and inflammatory responses. Interleukin 4 (IL-4) as an anti-inflammatory cytokine regulates balance between Th1 and Th2 immune responses. this study was undertaken to investigate the IL-1β and IL-4 genes polymorphisms in patients with systemic lupus erythematosus (SLE) and also association between the polymorphisms and susceptibility to SLE.

methodsOne hundred and sixty three SLE patients and 180 healthy controls were genotyped for the IL-4 VNTR (variable number tandem repeat), IL-1β C-511T and IL-1β T-31C polymorphisms by polymerase chain reaction (PCR) or PCR-RFLP (restriction fragment length polymorphism) method.

resultsThe frequencies of CC genotype and C allele of the IL-1β T-31C polymorphism were significantly (P<0.01) lower in SLE patients than controls. Moreover, the frequencies of RP1/RP2 genotype and RP2 allele of IL-4 VNTR polymorphism were significantly (P<0.05) higher in the SLE patients. No association was observed between IL-1β C-511T polymorphism and increased risk of SLE. We observed increased frequency of CT and TT genotypes of IL-1β C-511T polymorphism in SLE patients with malar rash compared to SLE patients without this manifestation. INTERPRETATION &

conclusionsThe present findings suggest that IL-1β T-31C and IL-4 VNTR polymorphisms but not IL-1β C-511T polymorphism may contribute in SLE pathogenesis. In addition, CT and TT genotypes of IL-1β C-511T polymorphism were associated with SLE.
