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

objectivesTo describe a set of complex walking tasks (CWTs) that can be used to evaluate mobility and to characterize age- and sex-specific performance on these tests.

designA population-based study of persons living in the Chianti geographic area (Tuscany, Italy).

settingCommunity.

participantsOne thousand two hundred twenty-seven persons (aged 20-95) selected from the city registries of Greve and Bagno a Ripoli (Tuscany, Italy). MEASUREMENTS: Gait velocity (m/s) was measured during 13 walking tests (Walking InCHIANTI Toolkit (WIT)) used to examine walking ability under a range of conditions and distances. Other measures included performance on the Short Physical Performance Battery and self-reported health and functional status, including disability in activities of daily living.

resultsAge-associated differences on the WIT were reflected in the number of older adults unable to complete CWTs and a decrease in gait velocity. For all tasks, decrements in walking speed with increasing age were significantly larger at aged 65 and older. Performance on CWTs was highly variable and could not be explained by usual gait speed measured under low-challenge conditions alone.

conclusionCWTs may provide important insight into mobility function, particularly in persons with normal or near-normal usual gait speed. Further research is needed to elucidate the specific physiological mechanisms that contribute to declining performance on CWT with increasing age.
