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/

aimsEthanol consumption is associated with an increased risk of esophageal cancer. The carcinogenic compound is acetaldehyde, the product of ethanol metabolism. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) are the main enzymes involved in ethanol metabolism, which leads to generation of acetaldehyde. In this study the activity of ADH isoenzymes and ALDH in esophageal cancer were compared with the activity in normal tissue.

methodsFor measurement of the activity of class I and II ADH isoenzymes and ALDH activity fluorimetric methods were employed. Total ADH activity and activity of class III and IV isoenzymes was measured by the photometric method. Samples were taken from 59 esophageal cancer patients (27 adenocarcinoma, 32 squamous cell cancer).

resultsThe total activity of ADH and activity of class IV ADH were significantly higher in cancer cells than in healthy tissues. The other tested classes of ADH showed a tendency toward higher activity in cancer than in normal cells. Differences between the activity of enzymes of drinkers and non-drinkers in both cancer and healthy tissue were not significant.

conclusionIncreased ADH IV activity may be a factor intensifying carcinogenesis, because of the increased ability to form acetaldehyde from ethanol.
