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
Manual aspiration thrombectomy (MAT) is a catheter intervention for cases with a high risk of bleeding. It is a rapid, simple, inexpensive, and single-session intervention for patients with proximal deep vein thrombosis (DVT). We evaluated the long-term outcome of MAT for patients with proximal DVT. All consecutive patients with acute proximal DVT treated at our center from April 2012 to December 2022 were retrospectively screened. Twenty-one patients who underwent MAT were enrolled. We evaluated the incidence and clinical characteristics of post-thrombotic syndrome (PTS) post-MAT in the chronic phase. The venous clot burden extent was assessed using the venographic segment (VS) score during catheter intervention. We evaluated the pre- and post-treatment total VS score. PTS was evaluated by PTS onset at any time between 6 and 24 months. We compared the clinical characteristics of patients with and without PTS (PTS and non-PTS groups, respectively). PTS onset at any time between 6 and 24 months post-MAT was 33%. The PTS group had a significantly higher post-treatment total VS score and lower thrombus aspiration success rate than the non-PTS group. Furthermore, the PTS group had a significantly longer duration from onset to intervention than the non-PTS group. PTS onset post-MAT was 33% in the chronic phase. The PTS group showed a lower thrombus aspiration success rate and longer duration from DVT onset to intervention than the non-PTS group. These findings suggest that earlier and substantial thrombus reduction with MAT may be associated with a lower risk of PTS.
