The Impact of the Russo‑Ukrainian War on Ukrainian Scholarly Publishing and Research Directions: A Bibliometric Analysis.
Article in Acta medica academica, 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
objectiveRussia's aggression against Ukraine has unfolded in two phases: the onset of the Donbas war and the annexation of Crimea in 2014, and the full-scale invasion in 2022. We examined the changes in Ukrainian scholarly publishing across these disruption periods.
methodsUsing Web of Science Core Collection and InCites data (1991-2024), we analyzed publication trends in Ukraine and Croatia, disciplinary composition, leading universities, city-level output in occupied territories, and international collaboration. Interrupted time series (ITS) models were specified with breakpoints at 2014 and 2022.
resultsUkraine's output increased from 331 articles in 1991 to 12,475 in 2021, then declined by 14.6% to 10,649 in 2024, whereas Croatia's output remained comparatively stable. The segmented ITS showed significant growth before 2014, a steeper upward trend after 2014, and a decline after 2022. Croatia showed continued growth with a smaller, non-significant post-2022 slowdown. In Ukraine, the largest post-2022 declines were observed in Physical Sciences and Social Sciences, while Engineering and Technology appeared more resilient. City-level analyses in occupied territories showed an early break in 2014 in Donetsk and Luhansk, while output linked to Simferopol and Sevastopol was rapidly reclassified after 2014, with records increasingly indexed under Russia. After 2022, collaboration with Russia collapsed, whereas partnerships with Poland, Germany, and the USA expanded.
conclusionUkrainian scholarly publishing showed phase-specific shifts in output and collaboration patterns that coincided with major geopolitical disruptions.
