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

introductionWe investigated the associations between -174 G/C polymorphism of interleukin-6 (IL-6) gene promoter and serum IL-6 and carcinoembryonic antigen (CEA) levels in Taiwanese patients with colorectal cancer (CRC). RESULTS AND DISCUSSION: The frequency of the G allele was only 0.043, which is significantly lower compared to Western analogs. On grouping genotypes as G-positive (GG and CG) and G-negative (GG), the average IL-6 level and CEA levels were significantly lower in G-positive patients than in G-negative analogs (IL-6, 3.56 +/- 4.38 vs. 15.38 +/- 9.52 pg/ml, P = 0.021; CEA, 27.7 +/- 25.7 vs. 157.7 +/- 59.6 ng/ml, P = 0.012). The patients without the G allele had higher incidences of synchronous cancers of other origins (P = 0.003).

conclusionIn conclusion, ethnicity affects the status of -174 G/C IL-6 polymorphism. This polymorphism status consequently influences the expressions of serum IL-6 and CEA and incidences of synchronous cancers of other origins.
