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

purposeTo identify whether variability in limb movement velocity during high-speed power training (HSPT) may impact physical functioning in older adults.

methods42 older men and women (71.3 ± 6.6 years) were randomized to lower extremity HSPT (n = 28) or control (CON; n = 14) (Analysis 1) for 12 weeks. A second analysis (Analysis 2) allocated HSPT into high-velocity (n = 14) or low-velocity (n = 14) based on a limb movement speed above or below the median average velocity during the 12-week HSPT intervention. Habitual gait speed, maximal gait speed, timed up-and-go, and the short physical performance battery were measured at baseline and 12 weeks. Change scores were compared between HSPT and CON (Analysis 1), and high-velocity, low-velocity, and CON (Analysis 2) using ANCOVA. Statistical significance was accepted at p < 0.05.

resultsAnalysis 1 There were no group differences in habitual gait speed, maximal gait speed, or timed up-and-go between HSPT and CON (all p > 0.05). Short physical performance battery was greater in HSPT (0.96 ± 0.19) compared to CON (0.10 ± 0.26; p = 0.01). Analysis 2 There were no group differences in the change in habitual GS (p = 0.33) among high-velocity, low-velocity and CON. There were significant group differences in the change in maximal GS (p = 0.007), timed up-and-go (p = 0.03), and short physical performance battery (p = 0.03).

conclusionsThere is considerable variation in self-selected maximal limb velocity during HSPT in older adults. In the present cohort, an average limb velocity of 0.88 m/s during HSPT was necessary to ensure optimal improvement in functional performance for older adults, but this threshold will need further investigation.
