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
The global population is aging at an increasing rate, and appropriate environmental design is crucial for the mental well-being of older adults. However, the associations between spatial configuration and psychological well-being in older adults remain insufficiently understood. To this end, a methodology integrating VR with structured participatory preference refinement was hereby proposed to assess the short-term psychophysiological responses and immediate affective states of older adults under simulated spatial configuration changes. Through conducting two semi-structured interviews with 50 elderly individuals, seven key design characteristics were identified, including ceiling height, spatial openness, natural light intensity and indoor noise levels. These insights were then translated into quantifiable experimental variables using empathy mapping and dual-cycle participatory design methodologies. Subsequently, a randomised experiment involving 18 VR scenarios was designed and 40 elderly individuals were selected as participants. Their physiological parameters (skin conductance level and heart rate) and psychological responses (measured using PANAS) were recorded. The results provide preliminary exploratory evidence suggesting associations between natural light intensity, indoor noise levels, spatial openness and older adults' short-term psychophysiological responses. These findings should be interpreted as hypothesis-generating rather than confirmatory, due to the non-independence of repeated-measures data and the exploratory nature of the orthogonal screening design. These results align broadly with prior literature, and the primary contribution of this study lies in its integrated methodological workflow. This study identified significant associations between spatial layout and short-term psychophysiological responses as well as immediate affective states in older adults. It supports the feasibility of integrating VR and participatory design, and provides observed associations and plausible interpretations for future age-friendly environment research.
