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
introductionMechanical thrombectomy (MT) for medium vessel occlusions (MeVO) is emerging as a promising treatment in acute stroke. We aim to evaluate the utility of additional imaging (CTP) in patients with MeVOs who received thrombolysis at a spoke hospital and were transferred to the hub.
methodsThis was a retrospective review of prospectively collected data from April 2018 to June 2023. Patients were transferred to one of the following destinations: CT scanner for a perfusion scan, directly to the angiography suite, or admitted to the neurological intensive care unit (NICU). We compared baseline characteristics, MT times, radiographic and clinical outcomes between the group that was initially transferred to CTP vs. the group that was not initially transferred to CTP.
resultsSeventy-eight MeVO patients who received IV thrombolysis and were transferred to our comprehensive stroke center were included in the analysis. Forty patients went directly to CTP, thirty went directly to the angiography suite (DTA), and eight were transferred to the NICU. 67.5% of patients presenting to CTP did not subsequently go to the angiography suite. The CTP and non-CTP groups did not differ significantly in terms of demographics, rates of successful recanalization, complications, and clinical outcomes at 90 days. The CTP group had significantly longer median door-to-groin times and median door-to-recanalization times.
conclusionMechanical thrombectomy should be considered in stroke patients with confirmed medium vessel occlusions who receive thrombolysis. CTP utilization may lead to lower angiography utilization and longer door-to-procedure times but does not significantly affect long-term outcomes.
