The influence of the lunar cycle on psychiatric emergency consultations: myth or reality?
Article in International journal of emergency medicine, 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
introductionThe notion that the moon exerts an influence on human behavior has long been a topic of interest. A number of studies have been conducted, yielding results that are, at least in part, contradictory. In this context, the objective of this study is to examine the impact of the lunar cycle on psychiatric emergency consultations.
methodsThis retrospective study analyzed 69,764 psychiatric consultations at the Centre Psychiatrique d’Orientation et d’Accueil, one of the largest psychiatric emergency departments in France, between 2016 and 2023. The data set comprised age, gender, reasons for consultations, diagnosis, disposition at the end of the consultation and lunar phases. The data were analyzed using four operational definitions of lunar exposure to ensure comparability with previous studies.
resultsNo statistically significant correlation was identified between the phases of the lunar cycle and the number of consultations or hospital admissions. No trend was observed in relation to reasons for consultations or specific psychiatric disorders, regardless of the definition used.
conclusionThe results confirm no significant influence of the lunar cycle on psychiatric emergencies, in line with the majority of existing studies. Despite popular beliefs, the study suggests that the moon has no effect on the number of emergency room consultations or the nature of psychiatric disorders, reinforcing the idea that such beliefs are scientifically unfounded at least at population level.
