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

Education grants often target audiences that have limited-resources relative to their peers, such as beginning farmers, who arguably have the most to gain from more education. Yet, charging even modest fees to these participants is discouraged, creating a challenge for funding entities that desire to have a dollar value for the education provided. To measure this value, we conducted an experiment using a willingness-to-accept (WTA) approach. Participants chose a minimum cash payout from seven different options to voluntarily leave a training session before receiving any instruction or educational materials. The design is constructed so that each option has an equal expected payout. Cash payouts were not advertised or known to any participants before the training. Results show that average WTA values are $277.44 per training (about 4 hours of instruction), which is 2.11 to 4.74 times more than participants' self-reported willingness to pay (WTP), depending on how travel costs and time of participants are valued. WTP consistently and significantly explains much of the variation in WTA. In sharp contrast, detailed travel cost estimates in various forms were consistently insignificant for explaining WTA values. Beginning farmers and ranchers, our targeted limited-resource audience, reported WTA and WTP values that were $81.18 and $22.73 more per training, respectively, than those of non-beginning farmers.
