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
BackgroundAspiration thrombectomy has become a standard tool for clot extraction in ischemic stroke. The ALGO Smart Pump (Von Vascular, Sunrise, FL) utilizes novel non-continuous aspiration and real-time objective data with the intent of increasing clot ingestion and first-pass effect while reducing distal emboli and time to reperfusion.MethodsFive different catheters were used to test clot extraction with the ALGO pump in a Mentice flow model. Clot extraction time, clot length, clot lodging or "corking" within the catheter, first-pass effect, distal embolization, and catheter distortion were assessed for each thrombectomy procedure. Thirty thrombectomies were performed with each catheter for a total of 150 thrombectomies.ResultsAll trials achieved reperfusion on the first pass. Complete clot ingestion with resumption of free flow through the catheter was seen in 65.3% of trials, with the remainder involving corking of the clot in the catheter or at the catheter tip. When the clot became corked, 63.3% of the time it was corked completely within the catheter; in the other 36.7%, the clot was corked at the catheter tip. Distal emboli were seen in 3.3% of trials. No evidence of catheter distortion was observed.Discussion/ConclusionThe ALGO non-continuous aspiration pump is effective at clot extraction with a wide range of catheters in the in vitro model. The low incidence of catheter tip-corking and distal emboli as well as the high first-pass reperfusion rate suggests the possibility of improved reperfusion with non-continuous aspiration.
