Brief communication: use of the minimal important difference for a meta-analysis on exercise and anxiety in adults with arthritis.

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
A recent meta-analysis reported statistically significant improvements in anxiety as a result of exercise in adults with arthritis and other rheumatic diseases (AORD) using the traditional standardized mean difference (SMD) effect size (ES). The objective of this study was to use the more recently developed and clinically relevant minimal important difference (MID) approach to examine this association. Data from a previous meta-analysis of 14 randomized controlled trials representing 926 initially enrolled adults ≥ 18 years of age (539 exercise, 387 control) was used to calculate the ES using the MID approach. Minimal important difference data were derived from previously reported anchor-based values that represented the different instruments used to assess anxiety. Effect sizes were pooled using the inverse heterogeneity (IVhet) model. Overall, exercise resulted in a mean ES reduction in anxiety of - 0.80 (95% CI, - 1.60 to 0.001, p = 0.05; Q = 92.1, p < 0.001, I
