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

Reachable workspace (RWS) quantifies the three-dimensional space accessible to the upper limb, but its relationship with real-world arm use after stroke remains unclear. This study examined associations between camera-based RWS and smartwatch-derived movement behavior in 14 individuals with chronic stroke. Relative surface area (RSA) was measured at baseline, after which participants wore a smartwatch on the affected arm. Smartwatch data were summarized using Gross Movement and Activity Count (GMAC), representing the proportion of wear time spent in active arm movement within a functional workspace, and Active and Diverse Exploratory Movement (ADEM), representing the proportion of wear time that was active and diverse. Clinical outcomes included the Box and Block Test (BBT), Upper-Extremity Fugl-Meyer Assessment (UEFM), and Motor Activity Log (MAL). Total RSA and several workspace regions were reduced in the paretic compared with the nonparetic limb. Greater total RSA was significantly associated with ADEM (ρ = 0.66,
