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
introductionSince the cold war, the population have not felt so much fear about the outbreak of the Third World War, sensation revived with the conflict between Russia and Ukraine.
objectiveThe aim is to validate a test in Latin America that measures fear perception and concern about a world war. METHODOLOGY: It is an instrumental study using Google Forms. It obtained 1684 participants in eight countries in Latin America. The creation of the first instrument was based on previous questionnaires that measured fear in the face of unexpected events, and other specific questions were added in the context of the war. Subsequently, the entire validation process was carried out. It was calculated the values of skewness, kurtosis, and communalities.
resultsExploratory factor analysis showed that two factors were generated, confirmed by the Kaiser-Meyer-Olkin test (KMO = 0,962) and Barlett's test (19558.5; df = 78; p = 0.000). Confirmatory factor analysis yielded seven items in two factors (χ DISCUSSION: The final instrument with seven questions allows to measure adequately general fear (factor 1), and physical and mental repercussions due to the possibility of the outbreak of a world war (factor 2).
