Association between Central Nervous System Drugs and Femoral Fracture Risk in Japanese Individuals ≥80 Years Old: A Case-crossover Study.
Article in Internal medicine (Tokyo, Japan), 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
Objective To assess the association between concomitant use of central nervous system drugs and femoral fracture risk in individuals ≥80 years old in Japan. Methods A case-crossover design was used, defining the case period as 3 days before the fracture diagnosis and the control period as 31-33, 34-36, and 37-39 days prior. The association between the daily intake of central nervous system drugs (Anatomical Therapeutic Chemical codes) and fracture risk was analyzed using conditional logistic regression. Patients Using the Japanese administrative claims database, we examined elderly patients diagnosed with femoral neck fractures between January 1, 2009, and December 31, 2020. Results In 255,875 patients, the concomitant use of central nervous system drugs increased the odds ratios of femoral fracture [3.41 (95% confidence interval: 3.27-3.55), 3.69 (3.46-3.91), 3.76 (3.42-4.13), and 4.34 (3.86-4.86) for an intake of >0-1, >1-2, >2-3, and >3 central nervous system drugs, respectively]. Conclusion The concomitant use of central nervous system drugs is associated with an increased risk of femoral fractures in individuals ≥80 years old in Japan.
