1 · What the graph read from it

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.

2 · The registry

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

Following the experimental medicine approach, Diehl et al. (2023) demonstrated the malleability of negative views of aging (NVOA), self-efficacy beliefs, and exercise intention in middle-aged and older adults who participated in the AgingPLUS intervention program. The present study built on those findings and addressed (a) whether the intervention resulted in significant improvements in physical activity (PA) and (b) whether the purported mechanistic variables were significant mediators of the intervention's effects on PA outcomes. AgingPLUS used a randomized, single-blind control group design to implement the intervention in a sample of 335 adults aged 45-75 years. This study reports findings from 278 participants (
