Age-dependent diminution of female prognostic advantage in gastrointestinal stromal tumors: a retrospective cohort analysis.
Article in Frontiers in immunology, 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
Background: Sex and age are significant factors influencing the prognosis of various types of cancer. However, the impact of sex and age on the prognosis of gastrointestinal stromal tumors (GISTs) remains unclear. Investigating the interaction between sex and age may facilitate a more precise assessment of the prognosis of GISTs. Methods: A retrospective analysis was conducted on a cohort of 5318 patients with GISTs, utilizing the Cox regression model to analyze the disparities in disease-specific survival (DSS) across sex. Subsequently, the cohort after propensity score matching was employed to investigate the prognostic differences attributable to age variations, and restricted cubic spline analysis was utilized to assess the prognostic disparities associated with different sexes and ages in GIST. Results: This investigation demonstrated substantial sex-based disparities in the clinical characteristics of GIST. With respect to prognosis, males exhibited a significantly elevated hazard ratio (HR) for DSS in comparison to females (HR = 1.40, p<0.001), which persisted following multivariate (HR = 1.38, p=0.006) and propensity score matching analyses (HR = 1.36, p=0.014). Moreover, a significant interaction between age and sex was observed in predicting DSS, notably indicating that younger female subjects (≤50 years) demonstrated a more favorable prognosis relative to their male counterparts. Conclusions: Female patients with GIST exhibit a more favorable prognosis than males, with this advantage decreasing with advancing age.
