Effects of appearance modifications on oral presentation anxiety in video conferencing.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Oral presentations are considered to provoke high levels of anxiety, yet limited research has explored this phenomenon in the context of video conferences. Considering the feasibility of private facial filters in video calls and the impact of audience appearance on speakers' experiences, we propose modifying the visual representation of the audience to reduce oral presentation anxiety in video conferences. We found literature evidence supporting the effectiveness of both highly familiar appearances and attractive anime characters in reducing anxiety. Building on this, we conducted a real video presentation experiment with 45 participants, comparing the effects of these two visual modifications through physiological signals, behavioral data, and self-reported measures. The results showed that the appearance of a good friend as a facial filter more effectively alleviated self-perceived oral presentation anxiety and led to higher performance evaluations during one-on-one video conferences, confirming that a familiar audience is a more universally effective approach. On the other hand, the anime character primarily reduced the speaker's attention to the audience's gaze, potentially benefiting in reducing the pressure of being watched. By shedding light on the role of audience appearance in video conference anxiety, this study offers valuable insights and practical strategies for designing customized computer-mediated communication environments that enhance speaker comfort and confidence.
