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

There have been numerous studies linking complement components and the pathogenesis of systemic lupus erythematosus (SLE). This is due to their numerous roles in modulating immune responses in the human body. This study examined the association of C2 and C7 genetic polymorphisms with the susceptibility to SLE based on two separate cohorts of patient and control samples from Malaysia. The 28-bp deletion in the C2 exon-intron junction and single nucleotide polymorphism in the 3'untranslated region in the C7 genes were detected based on direct polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism, respectively. A total of 150 patient and 150 healthy control samples were screened, but there was no association detected between either genes. All individuals presented with null deletion in C2 genes, while the C allele and CC genotypes were most commonly scored. These overall results suggest a lack of strong association with the C2 and C7 gene polymorphisms to the susceptibility of SLE in the Malaysian population.
