Clinically Important Differences for Mobility Measures Derived from the Testosterone Trials.
Trial report in Journal of the American Geriatrics Society, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND/
objectivesAccurate estimates of clinically important difference (CID) are required for interpreting the clinical importance of treatments to improve physical function, but CID estimates vary in different disease populations. We determined the CID for two common measures of walking ability in mobility-limited older men.
designLongitudinal, multisite placebo-controlled trial. SETTING/
participantsMen enrolled in the Testosterone Trials who had self-reported mobility limitation and gait speed less than 1.2 m/second (n = 429). Testosterone- and placebo-allocated participants were combined for this study.
resultsMean changes from baseline, adjusting for time-in-intervention and site, were 29.6, 13.2, 12.5, -2.4, and -32.6 m for 6MWD, and 15.4, 7.2, 2.1, -3.4, and -7.2 for PF10 in men who reported their mobility was "very/much better," "little better," "no change," "little worse," or "much worse," respectively. CID estimates using regression, ROC, and eCDF varied from 5.0-29.6 m for 6MWD, and 5.0-15.2 points for PF10.
conclusionCID estimates vary by the population studied and by the method and precision of measurement. Increases of 16 to 30 m for 6MWD and 5 to 15 points for PF10 over 12 months appear to be clinically meaningful in mobility-limited, older hypogonadal men. These CID estimates may be useful in the design of efficacy trials of therapies to improve physical function.
