Long-term cannabidiol treatment did not restore bone microstructural defects in skeletally mature ovariectomized Sprague-Dawley rats.
Article in JBMR plus, 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
Cannabidiol (CBD) effects on bone metabolism in postmenopausal osteoporosis remain unclear. While endocannabinoids and phytocannabinoids bind to receptors in bone cells, direct evidence of CBD's bone-protective effects is lacking. We evaluated the effects of CBD on bone metabolism in ovariectomized (OVX) rat model of estrogen deficiency. Twelve-week study with treatment initiated 2 wk after the surgery was conducted. Five experimental groups were established: sham-operated with vehicle (SHM/VEH), sham with CBD (SHM/CBD5), OVX with vehicle (OVX/VEH), OVX with 17β-estradiol (OVX/E2), and OVX with CBD (OVX/CBD5). Cannabidiol was administered at 5 mg/kg/d via osmotic pumps. Micro-CT of the distal femur revealed that trabecular bone mass in OVX/CBD5 decreased similarly to OVX/VEH, indicating no protective effect. Serum bone turnover markers showed increased bone resorption in OVX/CBD5 compared to OVX/VEH. Gene expression analysis revealed that estrogen significantly reduced
