Duration Matters: Anticonvulsant Therapy Linked to Bone Loss in Interim Cross-Sectional Study.
Article in Consortium psychiatricum, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundAnticonvulsants are widely used in treating patients with mental and neurological disorders. Their long-term use increases the risk of a decrease in bone mineral density (BMD) and low-energy fractures. Despite the growing number of studies of drug-induced osteoporosis, the effect of anticonvulsants on bone microarchitecture remains poorly studied.
aimTo study the effect of treatment duration with different generations of anticonvulsants on bone mineral density and fracture risk.
methodsWe examined 100 adult patients with epilepsy who had been on anticonvulsants for more than 12 months and 58 healthy subjects who had never taken anticonvulsants. All the participants underwent a general clinical and neuropsychological assessment, as well as bone densitometry using quantitative computed tomography in three regions of interest (lumbar vertebrae L1, L2 and femoral neck).
resultsBMD reductions were observed in 47 patients (47%) taking anticonvulsants and 29 (50%) subjects in the control group. The mean duration of anticonvulsant therapy was 8.7 years (SD=8.05) in patients with normal BMD, 10.7 years (SD=7.07) in patients with osteopenia, and 9.5 years (SD=5.24) in patients with osteoporosis. Age was found to significantly affect BMD, while the duration of anticonvulsant therapy affected it to a lesser extent. Patients taking first-generation anticonvulsants had lower BMD (
conclusionLong-term treatment with conventional anticonvulsants adversely affects BMD and can lead to pathological bone resorption, increasing the risk of fractures in patients. New-generation anticonvulsants did not show any significant negative impact on BMD. The results of this study indicate the need for further research to better understand the effects of anticonvulsants on bone tissue.
