Incidence of Venous Thromboembolism After Surgery for Acute Stanford Type A Aortic Dissection.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background The incidence of postoperative deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE) following acute Stanford type A aortic dissection (AADA) has not been investigated. Therefore, this study aimed to determine the incidence and risk factors of DVT and PTE following AADA. Methods This study included all patients who underwent emergency surgery for AADA at Ayase Heart Hospital, Tokyo, Japan, between April 1, 2023, and October 31, 2025. We excluded patients with preoperative venous thromboembolism (VTE), those who could not undergo postoperative lower extremity venous ultrasonography, and those who were undergoing anticoagulant therapy at the time of the postoperative ultrasound examination. DVT was assessed using lower extremity venous ultrasonography immediately before surgery and on the second postoperative day. Patients with DVT on postoperative lower extremity venous ultrasonography were grouped into the DVT group, while those who did not have DVT were grouped into the non-DVT group. The primary endpoint was the incidence of DVT, and the secondary endpoint was the incidence of PTE. Results Ninety-three of the 115 cases were included in the analysis. The DVT and non-DVT groups comprised 15 (16.1%) and 78 patients (83.9%), respectively. The incidence of PTE was significantly higher in the DVT group than in the non-DVT group (two cases: 13.3% vs. 0 cases: 0%; p = 0.01; χ
