Effect of lunar phases on international normalized ratio in patients with deep vein thrombosis using warfarin.
Article in Journal of education and health promotion, 2025. 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
backgroundThis study aimed to investigate whether the different lunar phases have any effect on prothrombin time and international normalized ratio levels in patients diagnosed with deep vein thrombosis who are undergoing warfarin therapy. Understanding potential external influences, such as lunar phases, on anticoagulant therapy could provide new insights into optimizing patient outcomes. MATERIAL AND
methodsData were retrospectively analyzed from 1418 international normalized ratio records of 124 patients with deep vein thrombosis who received warfarin therapy between March 2017 and August 2023. The lunar phase data were integrated with the corresponding international normalized ratio results, and statistical analyses were performed. The Jonckheere-Terpstra test for ordered alternatives was used to detect trends, while the Pettitt test assessed the presence of change points in the data.
resultsAn increasing trend in international normalized ratio values was observed during the third quarter lunar phase. While this trend suggested a potential tendency toward statistical significance, it did not reach the threshold for significance (Jonckheere-Terpstra test:
conclusionAlthough not statistically significant, this retrospective cohort study demonstrated a potential shift toward elevated prothrombin time levels during the third quarter lunar phase. While the results do not provide definitive evidence, they highlight the need for further large-scale, multicenter studies to explore the potential relationship between lunar phases and fluctuations in international normalized ratio values in patients undergoing warfarin therapy. Such research may provide clinicians with additional insights into managing anticoagulant treatments effectively.
