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

backgroundThe Balance Intensity Scales (BIS) have been developed to measure the intensity of balance exercise in older adults.

objectiveThe objective was to determine whether the BIS for therapists (BIS-T) and for exercisers (BIS-E) are unidimensional measures of balance exercise intensity, able to be refined using the Rasch model into a hierarchical item order, and appropriately targeted for the older adult population with a variety of diagnoses in a range of exercise testing settings.

designThis was a scale development study using a pragmatic mixed-methods approach.

methodsOlder adult exercisers (n = 108) and their therapists (n = 33) were recruited from a large metropolitan health service and rated balance exercise tasks on the BIS-T and BIS-E in a single session.

resultsScores on both the BIS items and global effort ratings for therapists and exercisers had good correlation and demonstrated unidimensionality. The BIS-T and BIS-E demonstrated a hierarchical distribution of items that fit the Rasch model. The Person Separation Index was moderate (0.62) for the BIS-T but poor (0.33) for the BIS-E. LIMITATIONS: The limitations were that therapists in this study underprescribed high-intensity balance tasks.

conclusionsInitial validation of the BIS-T and the BIS-E demonstrated that these scales can be used for the measurement of balance exercise intensity in older adult populations. The BIS-T items and global effort ratings are recommended for use by therapists, and the global effort ratings are recommended for use by exercisers. Ongoing validation of both scales using high-intensity balance task ratings and different populations of older adults is recommended.
