Feasibility of mobile-based noncommunicable disease risk factor data collection using WhatsApp and interactive voice response in Colombia.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The global increase in mobile phone usage, specifically in low- and middle-income countries (LMICs) provides opportunities for making non-communicable disease (NCD) data collection more efficient and economical. We investigated the feasibility of WhatsApp surveys and compared their population representativeness and NCD risk factor estimates with interactive voice response (IVR) surveys in Colombia. Participants were randomized to receive the NCD survey either via IVR or WhatsApp as the survey mode. Adults aged 18 years and over with a working mobile phone were sampled using random digit dialing (RDD). The survey included questions on demographics, tobacco use, alcohol consumption, and diet, with the primary difference in study arms being that visual examples (e.g., showcards) were used in the WhatsApp survey. We compared the demographic representativeness and NCD indicator estimates of the two surveys using log-binomial regression. The study was conducted between March 8 and March 12, 2023. Approximately 627 completed IVR surveys and 602 completed WhatsApp surveys were analyzed from 127,592 IVR and 2,632 WhatsApp calls (from 245,620 IVR enrollment calls). Overall, the WhatsApp arm had a higher proportion of young (18-44-year-olds: 81.9% vs. 74.2%), high-school educated (90.0% vs. 80.9%), and urban residents (80.4% vs. 73.4%) than IVR respondents. The overall prevalence/mean of most studied indicators was similar. For instance, with an adjusted risk ratio of 1.08 (95% CI: 0.83-1.40), the prevalence of tobacco smoking was 14.4% (95% CI: 11.7-17.3) and 16.4% (95% CI: 13.6-19.7) among IVR (ref.) and WhatsApp arms, respectively. The prevalence/mean differed for only two indicators: "number of vegetable servings consumed per day" and "<5 servings of fruits and/or vegetables consumed per day." Despite the inclusion of images in WhatsApp surveys, only minor differences in NCD indicators were found compared to IVR. Persistent gaps in rural and older populations must be addressed to ensure equitable monitoring in Colombia.
