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 quantify the association of visual field (VF) damage on physical activity away-from-home, per away-from-home excursion, and at-home.

designProspective cohort study.

methodsAmong 229 participants with glaucoma or suspected glaucoma, the severity of VF damage was defined as average sensitivity within the integrated VF (IVF). Participants wore accelerometers and global positioning system trackers for 7 days to measure physical activity and characterize activity location. Multivariable negative binomial regressions were used to test whether away-from-home activity per day, physical activity per away-from-home excursion, and at-home activity per day varied by the severity of VF damage.

resultsEach 5-dB decrement in IVF sensitivity was associated with a lower number of away-from-home activities per day (18% less moderate and vigorous physical activity [MVPA] minutes/d, 95% confidence interval, 0.69-0.97) and physical activities per away-from-home excursion (20% less MVPA minutes/excursion, 95% confidence interval, 0.65-0.98). Similar findings were noted for other away-from-home activity measures (including active minutes/steps per day, or active minutes/steps per excursion). However, worse IVF sensitivity was not associated with measures of at-home activities (MVPA minutes/d, active minutes/d, and steps/d), time spent at or away from home, or excursions/wk (P > .1 for all).

conclusionsRestriction of physical activity in more patients with severe glaucoma results mostly from activity restriction outside the home environment. These findings highlight the importance of maintaining a safe home environment (where activity is less restricted) and increasing confidence to perform activity, particular high-intensity activity, when leaving the home amongst patients with glaucoma.
