Thrombectomy aspiration post-market study in acute stroke with the Q aspiration catheter: the TAPAS study.
Observational study in Journal of neurointerventional surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04089917 (An Observational Study of the Q Aspiration Catheter Used During Neurointervention for Acute Large Vessel Ischemic Stroke in Spain.), which is not on this map.

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.

Abstract
backgroundThe Q Aspiration Catheter (MIVI Neuro) has demonstrated greater aspiration flow rates and ingestion forces compared with conventional catheters in vitro. The safety and performance of the Q Catheter was assessed using a direct aspiration first pass technique in patients with acute ischemic stroke at four neurointerventional centers in Spain.
methodsWe included adult patients who underwent mechanical thrombectomy between March 2019 and March 2020 using the Q Catheter as first-line therapy. Performance endpoints included final successful revascularization of the target vessel (defined as modified thrombolysis in cerebral infarction (mTICI) grade 2B/3), first pass revascularization, and overall Q Catheter revascularization. Safety endpoints were symptomatic intracranial hemorrhage (sICH), embolization to new territory (ENT), and procedural complications. Modified Rankin Scale (mRS) score and all-cause mortality were also assessed.
resultsForty-five subjects were enrolled. The Q Catheter successfully navigated to the lesion in 95.5% (43/45) of patients. Final successful mTICI 2B/3 revascularization was achieved in 93.3% (42/45), first pass mTICI 2B/3 revascularization with the Q Catheter was 55.3% (21/38), and overall with Q Catheter mTICI 2B/3 revascularization was 65.8% (25/38). Favorable clinical outcome of mRS 0-2 was achieved in 55.6% (25/45). There were no cases of ENT. sICH and mortality rates were 2.2% (1/45) and 13.3% (6/45), respectively.
conclusionIn this multicenter, observational study, the Q Aspiration Catheter used as first-line therapy demonstrated a good and safe profile in terms of navigation, revascularization, and safety in patients with acute ischemic stroke.
