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: Systemic thrombolysis is often not an option for elderly patients with PE because of bleeding risk. Large-bore catheters (16F-24F) can injure fragile vessels. The 6F Guidezilla guide extension catheter, already used in coronary cases, offers a smaller-caliber choice for thrombus aspiration and local thrombolysis. We report six elderly patients with high-risk PE treated with this approach. Methods: Six consecutive patients with intermediate-high or high-risk PE underwent thrombus aspiration and Results: The mean age of the patients was 75.8 ± 4.6 years (range 70-81 years), with five patients aged ≥70 years. One patient presented with high-risk PE (shock), and the remaining five were classified as intermediate-high risk. The mean simplified Pulmonary Embolism Severity Index (sPESI) score was 2.7 ± 1.2. The mean Miller score decreased significantly from 18.0 ± 6.7 pre-procedure to 5.2 ± 3.6 post-procedure ( Conclusion: The 6F Guidezilla catheter appears safe and effective for thrombus aspiration and
