Ground-based travel to European academic events as an alternative to air travel: Estimating associated greenhouse gas emissions, time and cost.

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
Objectives: We aimed to identify the number of participants at three differently situated scientific events in Europe realistically able to switch from aviation to ground-based travel, modelling the potential impact of doing so in terms of travel-related greenhouse gas emissions (GHGe), time and costs. Study design: Modelling study. Methods: Travel for participants (N = 137) attending three academic European events in 2025, two centrally, and one peripherally located, was simulated, estimating the associated GHGe, time and cost. Alternative travel scenarios (air- and ground-based), in which participants realistically switched to ground-based travel, were modelled, highlighting differences in travel-related GHGe, time and costs. Results: For this cohort, a central European location gave around 50 % of participants the opportunity to take ground-based travel, reducing total travel GHGe by a maximum of 29 % (14,116 kg of CO Conclusions: The potential to minimise travel-related, event-driven GHGe is driven by the distance from the participants' departing cities to arrival venue, and the number of participants who live within 1000 kms and/or one day's travel time by ground-based means. The ability to realise these GHGe reductions will depend on the extent to which eligible event participants may choose to shift from aviation to ground-based alternatives, driven by their capabilities to navigate such journeys (that may be more complex), and their motivation, which might be enhanced through financial incentives where ground-based transportation is more expensive.
