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
Destination therapy (DT) using an implantable left ventricular assist device (i-LVAD) in Japan has expanded treatment options for patients with out-of-hospital cardiac arrest (OHCA) receiving extracorporeal cardiopulmonary resuscitation (ECPR). However, achieving hemodynamic stabilization and improved peripheral organ perfusion is essential. In patients with OHCA, percutaneous mechanical circulatory support (MCS) devices may be inadequate in some cases, necessitating surgical MCS. Despite the growing importance of MCS upgrading, awareness among Japanese emergency physicians remains unclear. We aimed to assess awareness of advanced MCS upgrading strategies in refractory patients after ECPR. A nationwide survey of 293 emergency and critical care centers in Japan assessed awareness of i-LVAD therapy after ECPR. The questionnaire collected data on demographics, LVAD strategy recognition, MCS upgrade practices, and barriers. Of 90 facilities (31%) that responded, 87 (30%) consented to using their responses in the analysis. Awareness of DT was 59.8%. Notably, 66.7% and 70.1% of the respondents recognized that MCS upgrading could lead to i-LVAD treatment and heart transplantation, respectively. The major barrier to MCS upgrade therapy was the facility's inability to implement it. DT awareness was similar between IMPELLA-registered and non-registered facilities, but i-LVAD indication recognition was higher in IMPELLA-registered facilities (78.0% vs. 51.4%, P = 0.009). The low survey response rate suggests limited MCS upgrade awareness among Japanese emergency physicians. Although facilities recognize pathways to i-LVAD and transplantation, barriers to their implementation persist. IMPELLA-registered facilities showed higher i-LVAD indication recognition, reflecting their accessibility to LV unloading devices and connections with backup hospitals.
