Assessing response to stressful emotions: a controlled crossover study using pupillometry.
Article in Porto biomedical journal. 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
Background: Fear and horror induce autonomic protective responses, acting as "survival intelligence." Pupillometry is an innovative method that captures real-time autonomic nervous system reactions to stress. Objective: To evaluate the feasibility of pupillometry to assess the acute response to a passive real-life stressor-viewing a truthful war scene. Methods: Thirteen medical students (10 women) with an average age of 20.4 years were enrolled in a nonrandomized controlled crossover trial. Selected clips from two different audiovisual stimuli (M1: Results: A significant difference in response to acute fear and horror-induced stress was observed in pupillometry parameters {baseline [6.90 (5.95; 7.40) vs. 6.60 (5.55; 7.10), Conclusion: Our proof-of-concept study suggests that pupillometry may be used to evaluate changes in the activity of the autonomic nervous system induced by an acute passive stress stimulus.
