Testing certain and uncertain incentives on study retention in a longitudinal social media survey among young adults: An embedded recruitment trial.

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
Introduction: Incentives can be effective in survey research but evidence is limited on how incentive type impacts survey retention in longitudinal social media-based surveys. This study examined how certain and uncertain incentives affect study retention among US young adults recruited online and whether incentive effects vary by sociodemographic factors. Methods: Participants were randomized in a 1:1:1 ratio to a three-arm parallel trial ( Results: The certain CE was effective for survey retention versus the lottery at 30-day follow-up only (43.8% [lottery] vs. 77.7% [CE], AME: 0.346, Discussion: This study is among the few to experimentally test incentives for retention in online social-media based research. A certain CE was most effective for short-term web survey retention among young adults compared with a lottery. Findings suggest that small guaranteed rewards may better motivate study retention than uncertain larger amounts.
