From sky to sow: assessing the impact of drone-enabled semen delivery on pig fertility outcomes in rural Rwanda.
Article in Frontiers in veterinary science, 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
Introduction: Improving livestock productivity is vital for food security and rural incomes in Rwanda. Pig farming offers rapid income potential but is constrained by limited access to timely, high-quality artificial insemination (AI) services. To address this, the Rwanda Agriculture and Animal Resources Development Board (RAB), Zipline, and USAID's Orora Wihaze project piloted an aerial logistics model to distribute pig semen via drones, combined with training and awareness activities. This study evaluates the program's impact on AI outcomes among veterinarians, Community Animal Health Workers (CAHWs), and farmers across eight districts. Methods: A pre-post design with repeated cross-sectional surveys was conducted over 6 months. Baseline and endline surveys included veterinarians ( Results: AI performance improved significantly, especially among CAHWs, whose success rates rose from 48.8 to 74.8% ( Discussion: Drone-based semen delivery, paired with capacity-building, can improve reproductive outcomes, enhance last-mile delivery, and strengthen rural economies.
