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

Interferon Gamma gamma (IFN-γ) 13-CA-repeats polymorphism is associated with a variety of diseases; here we report its association with nasopharyngeal carcinoma (NPC) metastasis in a retrospective analysis of a cohort of 220 NPC patients in the northern China. The results showed that the distributions of CA13-/CA13-genotypes were significantly higher in the patients with lymph node metastasis (P<0.05) and distant metastasis (P<0.001); there was a significant difference between NPC patients with stage I+II and those with stage III+IV regarding CA13+/CA13-(P<0.001) and CA13-/CA13- genotypes (P<0.001); further analysis showed a more pronounced difference between NPC patients with stage I+II+III and those with stage IV for CA13-/CA13-genotype (P<0.001), whereas no difference was found for CA13+/CA13- genotype (P=0.790). Thus, we identify that IFN-γ 13-CA-repeat polymorphism is significantly associated with the metastasis of NPC, which may provide insights into its prognosis and individualized treatment.
