Effects of Combined Exercise and Calcium/Vitamin D Supplementation on Bone Mineral Density in Postmenopausal Women: A Systematic Review and Meta-Analysis.

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
backgroundPostmenopausal osteoporosis (PMO) is a major cause of fragility fractures worldwide. While exercise and calcium/vitamin D are standard preventive measures, the synergistic effects of their combined use on bone mineral density (BMD) remain unclear.
methodsWe systematically searched eight databases through October 2025 and synthesized data using Review Manager version 5.4. Subgroup, sensitivity, and meta-regression analyses were conducted to examine heterogeneity and test the robustness of results. Risk of bias was assessed using the Cochrane RoB 2.0 tool, and the certainty of evidence was graded with the GRADE framework.
results13 RCTs involving postmenopausal women were included. Compared with calcium and vitamin D supplementation alone, combined interventions significantly increased lumbar spine (SMD = 0.31, 95% CI [0.06, 0.55]) and femoral neck BMD (SMD = 0.47, 95% CI [0.09, 0.84]), with consistent but nonsignificant trends at other skeletal sites. Subgroup analyses showed that whole-body vibration produced the greatest and most consistent benefits at both sites, while mind-body or traditional Chinese exercises (e.g., Baduanjin) significantly improved lumbar spine BMD. Shorter interventions (≤6 months) yielded greater gains in BMD, whereas longer durations provided no additional advantage.
conclusionsExercise combined with calcium and vitamin D supplementation effectively improves bone mineral density in postmenopausal women, especially at the lumbar spine and femoral neck. Whole-body vibration and mind-body exercises show the greatest benefits, with short-term interventions proving most effective. This combined approach offers a practical, evidence-based strategy to preserve skeletal health in aging women.
