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
Introduction: Patients with esophageal cancer are at high risk of malnutrition, with family caregivers playing an indispensable role in nutritional management. However, the dynamic and heterogeneous changes of nutritional support needs of patients after radical esophagectomy, viewed from the perspectives of both patients and their caregivers, remain poorly understood. This may potentially hinder the development of timely and tailored interventions. Therefore, this study aimed to investigate the longitudinal trajectories of nutritional support needs within patient-caregiver dyads and identify distinct patterns of change over time, and explore associated influencing factors. Methods: This prospective longitudinal study recruited 159 patient-caregiver dyads from a tertiary hospital in Shanghai, China, between August 2024 and January 2025. Data were collected at four time points: pre-discharge (T1), 2 weeks (T2) post-discharge, 1 month (T3) post-discharge, and 3 months (T4) post-discharge. The Questionnaire of Nutritional Needs in Patients after Esophagectomy (QNN-E) was used to assess dyadic nutritional support needs. Trajectory homogeneity and heterogeneity were analyzed using latent growth curve modeling and latent class growth analysis. Baseline factors, including General Self-Efficacy Scale (GSES), quality of life (QLQ-OES18), Hospital Anxiety and Depression Scale (HADS), Activities of Daily Living (ADL), and Patient-Generated Subjective Global Assessment (PG-SGA), were examined as predictors of trajectory membership. Results: The nutritional support needs of patient-caregiver dyads declined over time. Significant heterogeneity was observed in therapeutic diet preparation, symptom surveillance and complication management. For therapeutic diet preparation, two distinct trajectories emerged in the patients ( Conclusion: The findings revealed significant heterogeneity in the postoperative nutritional support needs of patient-caregiver dyads, influenced by distinct factors. As primary providers of postoperative home-based nutritional care, caregivers' needs provide valuable insights for a more comprehensive understanding of postoperative nutritional care requirements. Continuity of nutritional care for patients with esophageal cancer should be grounded in dynamic and holistic assessments of their support needs, enabling personalized interventions at critical time points to improve postoperative recovery outcomes and care effectiveness.
