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
Aim: To evaluate the impact of assigning a dual-boarded emergency-psychiatry physician to the emergency department (ED) on the frequency, timing, and nature of psychiatric consultations. Access to psychiatric evaluations in EDs is often limited, particularly in Japan, where general hospitals with psychiatric services are declining. Integrating dual-boarded physicians in emergency medicine and psychiatry may address unmet psychiatric needs. Methods: This retrospective, single-center, pre-post study was conducted at a secondary emergency hospital in Tokyo, Japan. All patients transported by ambulance between October 2020 and September 2024 were included in this study. An a priori sample size calculation was not performed; instead, the study size was determined by all consecutive eligible patients during this predefined observation period. The intervention involved the continuous assignment of a dual-boarded physician in October 2022. The primary outcome was the number of psychiatric consultations initiated by emergency physicians. Secondary outcomes included reasons for consultation, patient characteristics, physiological indicators at ED presentation, emergency procedures at admission, consultation setting, time from admission to consultation, and clinical outcomes; for patients with multiple consultations during the same hospitalization, only the initial consultation was analyzed. Results: Among 23,916 patients, 137 psychiatric consultations were analyzed. Consultations increased 3.41-fold post-intervention (31 vs. 106), with the consultation rate increasing from 0.29% to 0.81%. High-risk psychiatric presentations, including suicidal ideation (40.6% vs. 12.9%, Conclusion: This study demonstrated that the 2-year assignment of one dual-boarded emergency-psychiatry physician was associated with an increased acceptance of more complex psychiatric cases in the ED, particularly those involving self-harm and suicidal ideation.
