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

backgroundThe incidence and mortality of colorectal cancer in Germany has declined in recent years. Nevertheless, colorectal cancer is still the second most common cancer in women (after breast cancer) and the third most common in men in Germany (after prostate cancer and lung cancer). Screening for colorectal cancer is well-established in many countries. The two most recommended screening strategies are colonoscopy and fecal immunochemical testing (FIT, stool test for occult blood).

objectiveThis article explains important conceptual and practical differences between the two strategies offered in Germany and summarizes the latest high-quality evidence for the benefits of the most frequently used screening tests. The aim is to provide physicians with decision aids for patients who show interest in colorectal cancer screening. MATERIAL AND

methodsConfirmed high-quality evidence from randomized trials on the benefits of screening for colorectal cancer with respect to incidence and mortality.

resultsThe lifetime risk to develop colorectal cancer in Germany is 5% for women and 6.5% for men. According to a large randomized trial, a screening colonoscopy reduces the risk of colorectal cancer from 1.2% to 0.8-0.9% after 10 years. New high-quality evidence from a recent Spanish randomized trial also showed that the benefits of FIT screening every other year are comparable to those of 1 colonoscopy over 10 years. The risks of perforation and bleeding during colonoscopy are 0.01% and 0.1%, respectively.

conclusionDuring the medical patient clarification on screening, it is recommended that the abovenamed facts on benefits and risks should be included and explained.
