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
Objective: To provide more accurate population estimates to support the operation of Bolivia's immunization program. Methods: This cross-sectional ecological study calculated population estimates using geospatial covariates extracted from Meta Data for Good and WorldPop satellite imagery, and validated them with the results of a microcensus conducted in five Bolivian municipalities. Results: Of the 6077 buildings identified in satellite images, 4505 residential buildings were found to be occupied. Of these, 3087 (68.52%) agreed to participate in the survey. A total of 17 617 people were expected and 13 397 were enumerated. Field enumeration identified fewer people under 30 years of age and more people over 60 years of age than expected. The Meta images provided excellent matches when analyzing population estimates by sex. Meta matched best with enumeration in rural areas, and WorldPop matched best with enumeration in urban areas. Conclusions: This study demonstrates that combining geospatial analysis with microcensus validation can significantly improve health planning, enabling equitable resource distribution and more effective immunization coverage.
