Under-Five Mortality in Humanitarian Emergencies: A Comparison of Face-to-Face and Mobile Phone Survey Estimates From Burkina Faso.
Article in Tropical medicine & international health : TM & IH, 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
objectivesWe evaluate the utility of mobile phone surveys (MPS) for estimating child mortality in Burkina Faso, where armed conflict and forced displacements hamper traditional face-to-face data collection on an important share of the territory.
methodsWe estimated under-five mortality from truncated birth histories collected in an MPS from September 2021 to October 2022. The sample consisted of telephone numbers collected in a prior face-to-face survey and an additional set of numbers generated through random digit dialling (RDD). We compared regionally disaggregated mortality estimates from the MPS with those from the 2021 Demographic and Health Survey (DHS), which could not cover parts of the national territory due to insecurity.
resultsOf 52,650 attempted phone numbers, 11,387 women of reproductive age were interviewed. Of these, 8077 were reached through RDD (36% lived in conflict-affected areas at the time of data collection) and 3310 via previously collected numbers (42% lived in conflict-affected areas). In regions not directly affected by conflict, under-five mortality rates have remained relatively stable over time: from 45 deaths per 1000 live births in 2018-2019 (95% CI: 36-54) to 58 in 2020-2022 (95% CI: 46-69). This finding mirrors the trend observed in the DHS data. In regions affected by armed conflict, however, the MPS data indicate a substantial increase in under-five mortality: From 47 deaths per 1000 live births in 2018-2019 (95% CI: 38-57) to 82 in 2020-2022 (95% CI: 67-98). This mortality reversal in conflict-affected areas is not apparent in the DHS, most likely due to the exclusion of the most insecure survey clusters from its sampling frame.
conclusionMPS offers a viable alternative or complement to traditional face-to-face surveys for estimating child mortality in populations where insecurity limits face-to-face survey data collection.
