From: Visual communication design in laboratory safety effectiveness and optimization of warning signs
Comparative Analysis of Warning Sign Optimization Effectiveness Across Laboratory Disciplines. Bars show percentage gains of optimized signs over baseline signs in four dimensions (visual perception, comprehension, memory, behavior) across four laboratory types (n = 120, pre–post design). Significance: *** p < 0.001, ** p < 0.01, * p < 0.05.
