Risk factors of osteoporosis in post-gastrectomy gastric cancer patients: a systematic review and meta-analysis.
Synthesis in Scientific reports, 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
Osteoporosis is a highly prevalent and serious complication among long-term survivors of gastric cancer (GC) after gastrectomy. However, the key risk factors predisposing patients to this condition have not been systematically assessed. PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched for observational studies from inception until July 21, 2025, to collect data on the risk factors for osteoporosis. Two independent reviewers appraised the methodological quality using the Newcastle-Ottawa Scale. Fixed-effects and random-effects models were used to calculate the odds ratio (OR) and 95% confidence interval (CI) for each factor. Eleven studies (covering 232,814 subjects) that reported clear associations were included in the analysis, the following risk factors were associated with osteoporosis in post-gastrectomy GC patients: female sex (number of studies [n] = 6; OR: 2.30, 95% CI: 1.50-3.51, p < 0.001), older age (n = 4; OR: 1.06, 95% CI: 1.03-1.09, p < 0.001), diabetes mellitus (n = 5; OR: 1.16, 95% CI: 1.07-1.25, p < 0.001), anemia (n = 2; OR: 2.20, 95% CI: 1.51-3.19, p < 0.001), elevated alkaline phosphatase (ALP) (n = 2; OR: 3.51, 95% CI: 1.35-9.12, p = 0.010), and Charlson Comorbidity Index score (CCI) > 3 (n = 2; OR: 1.24, 95% CI: 1.08-1.41, p = 0.002). Urban residence was associated with a modest protective effect (n = 2; HR: 0.87, 95% CI: 0.78-0.97, p = 0.013).
