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 AND

objectiveInterleukin (IL)-10 is a pleiotropic cytokine that can both stimulate and suppress the immune response. Previous studies have reported that IL-10 production was significantly elevated in cachectic patients, and it has been confirmed that polymorphisms of the IL10 gene could influence its expression. Therefore, we designed this study to investigate whether polymorphisms of the IL10 gene were associated with cachexia in patients with low-third gastric cancer in a Chinese population.

methods190 patients with low-third gastric cancer were included in this study. The serum levels of IL-10 were measured by radioimmunoassay. The single nucleotide polymorphisms (SNPs) at positions -1082A/G, -819T/C, and -592A/C in the IL10 gene promoter were analyzed using polymerase chain reaction (PCR) restriction fragment length polymorphism (PCR-RFLP).

resultsThe serum levels of IL-10 were significantly higher in patients with cachexia than in those without (Z = -10.66, p < 0.001). Single SNP analysis showed that the frequency of the IL10 -1082G allele was increased in patients with cachexia (p = 0.02). The -1082AG and -819CC genotypes were observed to be associated with an increased risk of cachexia. In a logistic regression analysis adjusted for actual weight and carcinoma stage, the -1082AG genotype was associated with an odds ratio (OR) of 2.45 (95% CI 1.21, 4.96; p = 0.01), and the -819CC genotype was associated with an OR of 3.70 (95% CI 1.20, 11.39; p = 0.02) for cachexia. Furthermore, haplotype analysis of the -1082A/G, -819T/C, and -592A/C SNPs revealed that at least five haplotypes (ATA, ACC, GCC, ACA, and ATC) were present in this Chinese population, and the -1082G/-819C/-592C (GCC) haplotype was associated with a significantly increased risk of cachexia as compared with the ATA haplotype (OR = 2.42; 95% CI 1.17, 5.00; p = 0.02).

conclusionOur results indicate that genetic polymorphisms of IL-10 may influence susceptibility to cachexia in patients with low-third gastric cancer in this Chinese population.
