Community consultation for exception from informed consent studies: are market research surveys representative of the target community populations?
Article in Trauma surgery & acute care open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: 'Exception from informed consent' research requires community consultation to ensure that the views of the local population have been considered. Using market research companies to distribute surveys across local populations is attractive because it ensures adequate response rates. It is not known whether individuals who respond to surveys are typical of the targeted communities. The purpose of this study is to compare the demographics of the survey respondents with that of the general population in the same area. Methods: This is an analysis of data collected as part of the 'Trauma Resuscitation with Group O Whole Blood or Products' (TROOP) trial. The surveys used a commercial market research service to reach the communities of interest and consisted of 18 questions designed to evaluate respondents' willingness to be enrolled in the TROOP trial and the demographics of survey respondents. Results: Catchment populations varied from 0.5 to 9.4 million residents, with a total of 33.5 million. The racial and ethnic composition of the population (and the survey respondents, in brackets) was 44.8% (57.0%) white, 25.7% (13.4%) Hispanic, 12.7% (19.4%) black, 8.0% (2.5%) multiracial, 7.9% (4.4%) Asian, 0.7% (0.9%) Native American, and 0.2% (0.5%) Islanders. Of the male population (and survey respondents, in brackets), 12.2% (15.3%) were aged 18years to 24 years, 20.5% (22.3%) aged 25 years to 34 years, 18.1% (24.9%) aged 35 years to 44 years, 16.3% (18.5%) aged 45 years to 54 years, 15.5% (14.8%) aged 55 years to 64 years, and 17.4% (4.3%) aged 65 years and over. Of the female population (and survey respondents, in brackets), 11.0% (18.5%) were aged 18 years to 24 years, 18.4% (22.6%) aged 25 years to 34 years, 16.4% (23.5%) aged 35 years to 44 years, 15.0% (17.3%) aged 45 years to 54 years, 18.5% (14.1%) aged 55 years to 64 years, and 20.6% (3.9%) aged 65 years and over. Conclusions: For this trial, using a market research company to distribute community surveys resulted in respondents that are broadly representative of the geographic areas where the trial will be conducted, except for individuals over the age of 65 years and older. This finding provides reassurance to investigators and institutional review boards that the views expressed by respondents are representative of the population where the trial will be conducted. Level of evidence: III.
