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
During natural disasters such as earthquakes, individuals are required to evacuate calmly amidst significant emotional distress, presenting a considerable challenge. Very few studies have measured emotional responses during disasters, and the emotional responses and brain activity during natural disasters are poorly understood. Therefore, this study aimed to investigate emotional responses during an earthquake using immersive virtual reality (VR), focusing on changes in neural connectivity in the left and right dorsolateral prefrontal cortices (DLPFCs). We measured changes in total haemoglobin concentration (Δtotal-Hb) using 2-channel near infrared spectroscopy (NIRS) while 24 healthy young adults viewed earthquake and neutral videos through a head-mounted display (HMD). Spearman's correlation analysis was applied to the time variation in Δtotal-Hb in the left and right DLPFCs, independently for seismic or neutral video conditions. The findings revealed a negative correlation between the left and right total haemoglobin concentration changes during the earthquake video (ρ = -0.53). Conversely, individuals exposed to the neutral video exhibited a positive correlation (ρ = 0.75). The present steady-state analysis suggests that emotional changes induced by virtual earthquake videos disturbed steady-state neural synchronisation between the left and right DLPFCs.
