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

backgroundPatients with colorectal cancer are at high risk of developing venous thromboembolism(VTE), and recent international guidelines have advised extended prophylaxis for some of these patients following surgery or during chemotherapy. However, our understanding of which patients are at increased risk, and to what extent, is limited.

objectivesTo determine absolute and relative rates of VTE among patients with colorectal cancer according to Dukes stage, surgical intervention,and chemotherapy.

methodsWe analyzed data from four linked databases from 1997 to 2006: the Clinical Practice Research Datalink, linked to Hospital Episode Statistics, Cancer Registry data, and Office for National Statistics cause of death data, all from England. Rates were compared by the use of Cox regression.

resultsThere were 10 309 patients with colorectal cancer, and 555 developed VTE (5.4%). The incidence varied by Dukes stage, being three-fold higher among Dukes D patients than among Dukes A patients (hazard ratio [HR] 3.08, 95% confidence interval [CI] 1.95–4.84), and 40% higher for those receiving chemotherapy than for those not receiving chemotherapy(HR 1.39, 95% CI 1.14–1.69). The risk following surgery varied by stage of disease and chemotherapy, with Dukes A patients having a low incidence of VTE (0.74%; 95% CI 0.28–1.95) at 6 months,with all events occurring within 28 days of surgery, as compared with Dukes B and Dukes C patients, whose risk at 6 months was ~ 2%.

conclusionTwenty-eight days of prophylaxis following surgery for colorectal cancer is appropriate for Dukes A patients. However, Dukes B and Dukes C patients receiving postoperative chemotherapy have a longer duration of risk.
