Tea consumption and bone health in postmenopausal women: a systematic review and meta-analysis.
Synthesis in Archives of osteoporosis, 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
objectiveThe impact of tea on bone health in postmenopausal women has generated conflicting opinions. The current study pooled previous research to evaluate the relationship between tea consumption and bone health in postmenopausal women.
methodsRelevant papers published before October 2024 were included by conducting a comprehensive literature search in the Embase, PubMed, Scopus, and The Cochrane Library databases. Observational studies reporting the association between tea consumption and bone mineral density (BMD) or the risk of osteoporosis and fractures in women after menopause were deemed eligible. The weighted mean difference (WMD) for BMD and the pooled odds ratio (OR) for osteoporosis and fractures were calculated, together with their corresponding 95% confidence intervals (CIs).
resultsThe meta-analysis examined 18 studies with a total of 48,615 individuals. The combined results indicated that postmenopausal women who consumed tea had higher BMD at several skeletal sites, including the lumbar spine (WMD, 0.02; 95% CI, 0.01-0.04; P < 0.001), greater trochanter (WMD, 0.02; 95% CI, 0.02-0.03; P < 0.001), femoral neck (WMD, 0.01; 95% CI, 0.00-0.02; P = 0.049), and ward's triangle (WMD, 0.02; 95% CI, 0.01-0.03; P = 0.002). Additionally, these women had a lower risk of osteoporosis (OR, 0.41; 95% CI, 0.26-0.67; P < 0.001) and fracture (OR, 0.81; 95% CI, 0.67-0.98; P = 0.031).
conclusionsThe findings of this meta-analysis suggest that postmenopausal women who regularly consumed tea saw an increase in BMD and a decreased likelihood of developing osteoporosis and experiencing fractures. Future research should give priority to conducting prospective cohort studies with a more stringent methodology to verify the dose-response connection between tea consumption and the risk of osteoporosis or fracture in postmenopausal women.
