Defaults at Work: A Field Experiment on the Effect of Nudges on Stand-Up Working.
Trial report in International journal of environmental research and public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Sedentary behavior at work is a major, and growing, public health concern. This field experiment investigates the effectiveness of behavioral nudges, specifically default settings on height-adjustable workstations (HAWS), in promoting stand-up working behavior. It also examines whether transparency and health coaching enhance these effects. The study was conducted in a Belgian governmental organization and included 149 employees across eight departments. Departments were randomly assigned to one of four conditions: a non-transparent default nudge (NTDN), a transparent default nudge (TDN), a classical health coaching intervention, or a hybrid intervention combining TDN and coaching. Over an eight-week intervention period, employee posture was recorded using fixed camera snapshots taken every 30 min. These data were used to calculate the stand-up ratio. The NTDN increased stand-up rates from 1.82% to 4.93%. The TDN more than doubled this effect, reaching 11.25%. The combination of TDN and coaching produced the highest increase, with stand-up rates rising to 18.80% (
