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.

Abstract

Pulmonary arterial hypertension (PAH) patients have low activity time. Actigraphy provides an objective quantification of movement outside of clinic visits (home, work, social activities). Summary actigraphy measures (total daily steps or activity time) have not been shown to increase after adding therapies in patients with PAH. We developed a novel treatment responsive metric, Peak Steps, to measure the 'capacity for movement' in patients with PAH. Using data from the ADAPT registry (NCT03045029), we calculated Peak Steps and used summary actigraphy measurements and correlated it with six-minute walk distance (6MWD) and emPHasis-10 quality of life scores. After exposure to oral treprostinil, we observed a significant increase in Peak Steps, but no change in total daily steps or activity time. Peak Steps correlated strongly with 6MWD and emPHasis-10 scores. We propose that Peak Steps is a more sensitive marker of treatment response than traditional actigraphy parameters, which can have large behavioral influences.
