Impact of antiphospholipid antibodies on thrombotic events in ambulatory cancer patients.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
backgroundDespite the conflicting data, the positivity of antiphospholipid antibodies (aPL) in cancer patients may be associated with an increased risk of thrombosis.
objectiveTo identify the prevalence and impact of aPL on venous thromboembolic events (VTE) and arterial thrombosis (ATE) in ambulatory cancer patients.
methodsIn this single-center, prospective cohort study, we enrolled newly diagnosed ambulatory cancer patients receiving chemotherapy. Non-cancer controls were age- and sex-matched. Participants were evaluated for aPL. Primary outcomes were the composite outcome of VTE or ATE and the prevalence of aPL positivity in cancer patients. Secondary outcomes included the risk of VTE and ATE in cancer patients and all-cause mortality at six-month follow-up duration.
resultsThere were 137 cases and 137 controls with mean age of 56.0±12.3 and 55.5±12.1 years, respectively. Cancer patients were more likely to have positive aPL compared to controls, with the risk difference of 9.4% (95%CI 1.5 to 17.5). Composite of ATE or VTE occurred in 9 (6.6%) in cancer patients and 2 (1.5%) in controls. Cancer patients with aPL positivity were associated with higher risk of ATE or VTE (risk ratio [RR] 3.6, 95% CI 1.04-12.4). Positive LA in cancer patients were associated with higher risk of composites of ATE or VTE (RR 5.3 95%CI 1.3-21.0), whereas the anti-β2-GPI positivity were associated with increased risk of VTE (RR 4.7, 95%CI 1.1-19.2).
conclusionaPL was more prevalent in active cancer patients and positive aPL in cancer patients was associated with arterial or venous thrombosis.
