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 Cancer-VTE Registry evaluates the occurrence and management of venous thromboembolism in Japanese participants with major solid tumors. Using Registry data, we evaluated the frequency of concurrent venous thromboembolism in cancer patients prior to treatment initiation by cancer type.

methodsThe Cancer-VTE Registry is an ongoing (March 2017-September 2020) prospective cohort study using a nationwide, multicentre clinical registry. Participants aged ≥20 years with colorectal, lung, stomach, pancreatic, breast or gynecologic cancer, confirmed staging, ≥6 months life expectancy post-registration and who had undergone venous thromboembolism screening were managed with routine clinical care. Venous thromboembolism frequency at registration was evaluated.

resultsOf 9735 participants, 571 (5.9%) had venous thromboembolism at baseline, including asymptomatic [5.5% (n = 540)] and symptomatic venous thromboembolism [0.3% (n = 31)]. Most participants with venous thromboembolism (n = 506, 5.2%) had deep vein thrombosis only; 65 (0.7%) had pulmonary embolism with/without deep vein thrombosis. The prevalence of distal and proximal deep vein thrombosis was 4.8% (n = 466) and 0.9% (n = 83), respectively. The highest prevalence of venous thromboembolism was for pancreatic cancer (8.5%) and the lowest for breast cancer (2.0%). Venous thromboembolism prevalence increased as cancer stage advanced.

conclusionsAlthough there was a marked difference in venous thromboembolism by cancer type, the data suggest that cancer stage is an important risk factor for venous thromboembolism. Thus, metastasis seems a critical risk factor for venous thromboembolism. This is the first demonstration of venous thromboembolism prevalence and risk factors in Japanese cancer patients prior to treatment.
