Heterogeneity in benefit finding among breast cancer patients: a latent profile analysis and influencing factors.
Article in Frontiers in oncology, 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
Objectives: This study investigates factors influencing benefit finding among breast cancer patients based on social cognitive theory and develops a nomogram to predict the probability of low benefit finding in breast cancer patients. Methods: A study of 666 breast cancer patients in northern Anhui Province (January to December 2024) employed latent profile analysis to identify distinct benefit finding patterns. Potential predictors were identified through univariate analysis, least absolute shrinkage and selection operator regression, and multivariate analysis. Five machine learning algorithms were applied to predict low benefit finding, with performance evaluated via calibration and discriminative power metrics and internally validated using bootstrap resampling. Results: A two-classification model best fits the data, identifying the low benefit finding category (35%) and the high benefit finding category (65%). XGBoost outperformed other models and was selected as the final model. The model achieved an AUC of 0.945 on the validation set. SHAP analysis quantified each variable's contribution to predictions, revealing age, medication adherence, anxiety, social support, and depression as key determinants of benefit finding. Conclusion: This study applied social cognitive theory to examine factors affecting benefit finding in breast cancer patients, focusing on environmental, individual, and behavioral domains. Results showed strong performance by the XGBoost classifier. The developed nomogram aids healthcare providers in swiftly identifying patients with low benefit finding, enabling personalized interventions to mitigate adverse psychological effects and improve long-term outcomes.
