Burden and distribution of venous thromboembolism across cancer types and stages: a meta-analysis of observational studies.

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
Introduction: Venous thromboembolism (VTE) is a serious life-threatening complication among patients with cancer. This systematic review and meta-analysis aimed to quantify the proportion of VTE across different cancer types, stages, and study settings. Methods: A comprehensive literature review was conducted to identify observational studies reporting VTE events in cancer patients. Studies were categorized into population-based and hospital-based settings to compare VTE prevalence. Cancer types were classified by anatomical origin, and cancer stages (Stage I-IV). Meta-analytic techniques were applied using R software, and pooled VTE proportions with 95% confidence intervals (CIs) were calculated. Heterogeneity was assessed using the I² statistic, and forest plots were generated for visualization. Sensitivity analyses were conducted to evaluate the robustness of findings. Results and discussion: The analysis included 14 studies, out of which hospital-based studies reported a significantly higher VTE proportion (4.1%) compared to population-based studies (2.9%) ( Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/view/CRD42024616005, identifier CRD42024616005.
