The effect of cash lottery on response rates to an online health survey among members of the Canadian Association of Retired Persons: a randomized experiment.
Trial report in Canadian journal of public health = Revue canadienne de sante publique. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 of them syntheses that pooled 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.
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
objectivesThe objectives of the study were 1) to assess the effect of cash lottery on participation rates in a web-based study of physical activity and joint health and 2) to compare recruitment via direct e-mail versus advertisement in an online newsletter.
methodsA sample of 1,150 individuals, randomly selected from a database of members of the Canadian Association of Retired Persons (CARP), was e-mailed a request to participate in an online survey, with follow-up e-mails after 1 and 2 weeks. The sample was randomly split into two groups. Half the sample was offered entry into a cash draw with a $500 grand prize and five $100 prizes, whereas the other half was not offered any incentive. In addition, a brief advertisement about the survey (without an incentive) was placed in an online newsletter that was circulated to 14,000 randomly selected CARP members.
resultsIn the incentive group, 305 (53.0%) clicked on the hyperlink and visited the website and 84 (14.6%) completed the survey. In the group who received no incentive, 280 (48.7%) clicked on the link and 59 (10.3%) completed the survey. Of those who received the online newsletter, 492 (3.5%) visited the website and 106 (0.76%) completed the survey.
conclusionA relatively modest financial incentive in the form of a cash lottery significantly increased participation rates in an online health survey. Recruitment through a newsletter advertisement had a very low yield compared to direct e-mail.
