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
Routine collection of behavioral and social drivers (BeSD) of vaccination data is essential for understanding and addressing vaccine confidence and demand to achieve high vaccination coverage. Traditional house-to-house data collection methods are resource-intensive, prompting the need for alternative, scalable approaches. This study tested the feasibility of using mobile phone surveys to collect community-level BeSD data on COVID-19 vaccination in Zambia. A cross-sectional survey of adults aged 18 and over was conducted in three districts: Lusaka, Kalomo, and Chavuma. Participants were recruited via geotargeted mobile phone messages and responded using push-button inputs. The survey adapted validated BeSD questions from the World Health Organization (WHO) framework and was administered in English and six local languages. Strategies to increase response rates were tested, including offering a small monetary incentive and conducting community outreach via radio jingles. To assess the feasibility of using mobile phone surveys to collect BeSD data, we report on response rates and the demographic distribution of respondents and describe the operational process of applying this methodology. From March to July 2024, a total of 52,983 recruitment messages were sent, yielding an overall response rate of 15.7%. Response rates varied by district, with Chavuma having the highest (68.2%) and Lusaka the lowest (4.2%). Compared to a baseline response rate of 4.7%, offering a monetary incentive increased the response rate to 31.4%, while community outreach increased it to 19.8%. Respondents skewed younger (69.5% aged 18-29 years) and male (65.9%). Mobile phone surveys present a feasible method for collecting real-time BeSD data at the community level in low-resource settings. Incentives and community outreach effectively increase participation, though results may need to be weighted to reflect population demographics.
