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

backgroundDenosumab, a bone-modifying agent, reduces the incidence of skeletal-related events (SREs), but its optimal use in real-world metastatic castration-resistant prostate cancer (mCRPC) settings remains unclear.

methodsWe conducted a retrospective cohort study of 235 patients with bone mCRPC treated with denosumab between 2015 and 2024. The primary endpoint was identification of risk factors associated with symptomatic skeletal events (SSEs) after denosumab initiation. Secondary endpoints were risk factors for SREs occurring prior to denosumab. Multivariate Cox regression analyses assessed independent predictors.

resultsOver a median follow-up of 11 months, 27 patients (11.5%) developed an SSE. The most common events were EBRT to bone (7.7%) and pathologic fractures (4.3%). The 2-year SSE-free survival rate was 79.4%. A prior history of SREs was independently associated with a significantly increased risk of subsequent SSEs (hazard ratio [HR]: 2.09; 95% confidence interval: 1.02-4.92; p = 0.047). In a separate analysis of SREs occurring prior to denosumab, grade 2 and ≥ 3 disease at the time of bone metastasis diagnosis were associated with higher risk (HR: 2.62 and 2.32, respectively; both p < 0.05). Denosumab was discontinued in 62.6% of patients, primarily due to clinical deterioration, death, or difficulty attending appointments.

conclusionIn this real-world study, approximately 10% of patients with bone mCRPC developed SSEs during denosumab therapy, mostly within the first year. A prior SRE and high baseline bone tumor burden were significant predictors of skeletal complications, underscoring the importance of early risk stratification and timely initiation of bone-targeted therapies.
