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 RehaWatch® system is a portable accelerometer for measurement of gait parameters that shows good validity in young adults; however, validity data are missing for elderly persons in long-term care (LTC).

aimThe aim was to evaluate the concurrent validity of the RehaWatch® system using the GAITRite® system as a criterion reference for gait assessment in the LTC elderly. MATERIAL AND

methodsIn this study 23 elderly participants (mean age 90.9 ± 8.4 years) performed 4 walking trials at normal and fast walking speed during single task and dual task walking. Data for both systems were collected simultaneously for each trial. Concurrent validity was assessed through limits of agreement (LoA) methodology using Bland-Altman plots.

resultsNo systematic bias could be determined. Mean biases for step duration, velocity and cadence were above the prespecified ±7 % value from zero lines for normal walking during single task and dual task walking. The LoA had a wide range between -21 % and 25 %. Only cadence showed small LoA for normal walking speed during single (-8.4 % to 7.7 %) and dual tasking (-4.1 % to 3 %). Heterogeneous bias was determined for step duration during fast walking during dual task and for velocity during fast walking during single task and dual task. Heteroscedasticity was shown for step length during normal walking under the dual task condition and fast walking during single task and dual task activities.

conclusionNo gait parameters are interchangeably usable between the two systems for normal walking during single task and dual task activities.
