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.

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
Flattened bamboo boards are increasingly used in interior environments; however, their influences on users' perceptual and cognitive responses remain insufficiently understood. Using a sample of 25 participants, this study investigated the visual psychological impressions and neurocognitive processing associated with three types of flattened bamboo boards by integrating Semantic Differential (SD) evaluations with event-related potential (ERP) measurements. ERP analyses focused on the P300 component (300-500 ms) across frontal, central, parietal, and occipital regions. The results revealed clear perceptual and neural distinctions among the board types. The inner board consistently elicited the most positive perceptual impressions, being associated with naturalness, warmth, comfort, and delicacy, and was processed with the lowest cognitive load. In contrast, the outer board tended to be perceived as more artificial and decorative and evoked the highest P300 amplitude and longest latency, indicating greater cognitive effort and evaluative complexity. The bamboo outer layer board exhibited a more neutral and heterogeneous perceptual profile, with balanced evaluations of naturalness versus artificiality and exquisiteness versus roughness, while being more frequently associated with coolness and showing greater inter-individual variability in subjective evaluations. ERP analyses further demonstrated significant differences in P300 amplitude and latency across board types. While parietal P300 amplitudes differed significantly (
