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

objectiveThis study aims to investigate the effect of ω-3 fatty acid immunonutritional therapy on natural killer (NK) cell gene methylation and function in elderly patients with gastric cancer.

methodsA total of 70 cases of elderly patients with gastric cancer were randomized into the ω-3 fatty acid group and placebo group, according to the type of nutritional support administered. The methylation status of the tumor necrosis factor (TNF)-α gene promoter in peripheral NK cells was detected by methylation specific polymerase chain reaction, and the TNF-α level in peripheral NK cells was detected by enzyme-linked immunosorbent assay.

resultsAfter 14 days of immunonutritional therapy with ω-3 fatty acid or placebo, patients in the ω-3 group had significantly higher average NK cell activity (0.27 vs. 0.24, P=0.013) and lower percentages of TNF-α gene promoter methylation (25.7% vs. 60%, P<0.05) than the placebo group. However, there were no significant differences in the concentration of albumin, prealbumin and TNF-α in serum, and the NK cell count between the ω-3 group and placebo group.

conclusionThe postoperative application of ω-3 fatty acid may improve the activity of NK cells, which is correlated to the methylation status of the TNF-α gene promoter.
