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
Objective: Drawing on the Stimulus-Organism-Response framework, this mixed-methods research examines how specific mobile navigation architectures, namely complexity and diversity, shape older adults' cognitive load, affective states, and enduring digital self-efficacy. Methods: The study utilized a two-phase design. Phase 1 involved a cross-sectional survey of 285 community-dwelling older adults, applying Partial Least Squares Structural Equation Modeling to test parallel mediation pathways. Phase 2 conducted a within-subject usability experiment with 25 participants evaluating five common mobile navigation paradigms, pairing real-time emotion tracking via the PANAS scale with granular behavioral metrics. Results: The PLS-SEM analysis indicated that high navigation complexity significantly drives up cognitive load (β = 0.111, Conclusions: These findings highlight the limitations of relying solely on the traditional efficiency-first paradigm in usability evaluation. For older adults, establishing a psychological sense of control frequently outweighs mere interaction speed. To advance sustainable digital inclusion, designers should move beyond purely reductive interfaces and instead design supportive environments that accommodate behavioral heterogeneity and foster true cognitive engagement.
