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
Objective: Mechanical thrombectomy (MT) is an important procedure in the treatment of acute cerebral infarction, and its effectiveness depends largely on timely intervention after the onset. In the United States, a tiered accreditation system of stoke centers has been established to provide MT efficiently. In Japan, however, despite the large number of medical institutions performing MT, the establishment of a tiered accreditation system has yet to be seen. The low number of cases treated per institution raises concerns about the economic sustainability of MT in Japan because significant capital and human resource investment are required. This study aims to investigate the cost structure of MT procedure and the break-even point in 2 different hospital settings in Japan. Methods: We conducted a detailed cost analysis of MT at 2 distinct hospitals: Hospital A, a large public hospital in a government-designated city, and Hospital B, a private non-profit hospital in the Tokyo metropolitan area. Data collection involved face-to-face interviews with department heads and a structured survey based on the Japanese Hospital Accounting Standards, focusing on material, labor, and facility-related costs. Break-even points were calculated considering both fixed and variable costs, with adjustments made for the shared use of facilities in Hospital B. Results: The total cost per case was 349256 yen in Hospital A and 245150 yen in Hospital B, respectively. The total cost per case was elevated to 559866 yen assuming only MT was performed at Hospital B. This figure was significantly higher than the reimbursement price of MT (331500 yen). The number of procedures needed to exceed the break-even point for MT was approximately 290 cases per year in Hospital A and 125 cases per year in Hospital B, respectively. Conclusion: We conducted a break-even analysis of MT based on an interview survey. The number of cases required to cross the break-even point for MT alone was much higher than the actual number of MT procedures being performed in the 2 hospitals.
