1 · What the graph read from it

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.

2 · The registry

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

backgroundEarly-life exposure to famine has been hypothesized to influence long-term bone health, potentially increasing the risk of osteoporosis and fractures in later life. This systematic review and meta-analysis aimed to investigate the association between early-life famine exposure and the risk of osteoporosis, bone mineral density (BMD) loss, and fractures.

methodsA comprehensive literature search was conducted across MEDLINE/PubMed, Scopus, Web of Science, and Embase, supplemented by manual searches on Google Scholar. Observational studies examining the impact of early-life famine exposure on osteoporosis, BMD, and fracture risk were included. Data were extracted and quality assessed independently by two reviewers, and meta-analyses were performed using the Mantel-Haenszel method for odds ratios (OR) and Hedges' g for standardized mean differences (SMD). Heterogeneity was assessed using the I

resultsFrom 6147 initial studies, 10 met the inclusion criteria, with 8 included in the meta-analysis. The early-life famine-exposed group showed a significantly higher incidence of osteoporosis (OR = 2.12, 95%CI [1.35, 3.34], I

conclusionEarly-life famine exposure is significantly associated with an increased risk of osteoporosis, fractures, and lower BMD in later life. These results emphasize the lasting effects on bones from early lack of nutrition and stress the importance of specific interventions for bone health in groups with past famine experiences. Future studies should investigate the reasons behind these connections and assess preventative approaches to reduce the negative effects on bone health in those impacted.
