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

This study examines whether consumers' willingness to pay (WTP) for ready-to-eat cereals differs between immersive virtual reality (IVR) and real-world (RW) environments. Real choice experiments were conducted with 227 respondents who selected reservation dates without knowing whether they corresponded to the IVR or RW setting. To derive consumers' WTP, random parameter logit models were estimated primarily in WTP space, while preference-space models were used as a robustness check. The results show no significant differences in WTP between IVR and RW for any of the cereal products tested. This suggests that consumers' product choices in IVR environments are based on monetary valuations, similar to those in real environments. When combined with real economic incentives, IVR-based choice experiments may therefore yield WTP estimates comparable to those obtained from conventional real choice experiments. To our knowledge, this is the first study to compare WTP between IVR and RW environments using an incentive-compatible experimental design.
