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

purposeTo evaluate the molecular evolution of endoplasmic reticulum (ER) stress during colorectal cancer carcinogenesis.

methodsFifty-six hairless mice were divided into two groups: control (no intervention); and carcinogenesis (treated with two doses of azoxymethane at 10 mg/kg during the third and the fourth week and dextran sodium sulfate at 2.5% for seven days in the second, fifth, and eighth week). Euthanasia occurred at the fifth, 10th, 15th, and 20th week. Colons were collected, and gene expression of ER stress markers (IRE1-α, PERK, ATF6, and CHOP) was assessed via real-time quantitative polymerase chain reaction.

resultsERN1 expression was significantly higher than the control at the 10th week (1.39 ± 0.16, p 0.05) and the 20th week (1.15 ± 0.04, p 0.01). ATF6 also showed elevated expression, significantly different at the 10th week (1.71 ± 0.29, p 0.05) and the 20th week (1.14 ± 0.06, p 0.05). PERK and CHOP expressions were significantly higher than the control in the 15th (PERK = 1.30 ± 0.12, CHOP = 1.48 ± 0.23) and 20th weeks (PERK = 1.63 ± 0.20, CHOP = 1.67 ± 0.22, p 0.05).

conclusionUpregulation of IRN1, PERK, ATF6, and CHOP demonstrates a strong ER stress response during colorectal cancer development.
