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

Background: Greenland is an Arctic environment with snow and ice on uneven terrain posing lifelong physical challenges to people in Greenland. In addition, Greenlanders are a distinct ethnic group. This led us to (1) quantify reaction time among Greenlanders (2) hypothesising a faster reaction time compared to previous findings among e.g., Scandinavians. Methods: Data were collected using a portable device, the Nintendo Wii Balance Board, with the FysioMeter software validated for estimating reaction time. Participants were healthy Greenlanders living in West Greenland, who filled in a questionnaire on physical activity, disease, prescription medicine, alcohol, and smoking habits. Reaction time was measured for dominant and non-dominant upper and lower extremities. Results: The 72 women and 42 men participating had a mean age of 50 years, range 20 to 83 years. The age-related increase in reaction time was around 6 milliseconds for each year of advancing age ( Discussion: This first study of reaction time in Greenlanders found patterns similar to those observed in e.g., Scandinavians. Interestingly, Greenlanders did not demonstrate faster reaction times despite lifelong exposure to physically demanding and unstable terrain. This finding may be relevant for future research on motor adaptation and environmental influences on balance control.
