Association of Serum Progranulin Levels With Disease Progression, Therapy Response and Survival in Patients With Metastatic Breast Cancer.
Observational study in Clinical breast cancer, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05627960 (FIH Phase 1A /1B Study of AG01 Antibody Against Progranulin/GP88 in Advanced Solid Tumor Malignancies With Expansion Cohorts in Advanced Triple Negative Breast Ca, Hormone Resistant Breast Ca, Non Small Cell Lung Cancer and Mesothelioma), which is not on this map.

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.

Abstract
backgroundProgranulin (GP88) is a critical player in breast tumorigenesis. GP88 tumor expression is associated with increased recurrence and mortality, whereas GP88 circulating levels are elevated in patients with breast cancer compared with healthy individuals. We examined here the correlation between serum GP88 levels in patients with metastatic breast cancer (MBC) with overall survival and disease status determined as response to therapy or progression of disease. PATIENTS AND
methodsAn institutional review board (IRB)-approved study prospectively enrolled 101 patients with MBC at the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center. GP88 serum levels were correlated with patients' disease status determined by Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria and survival outcomes by Kaplan-Meier analysis and log rank statistics.
resultsPatients' survival was stratified by serum GP88 level. Patients with serum GP88 < 55 ng/mL had a 4-fold increased survival compared with patients with GP88 > 55 ng/mL. Examination of GP88 serum levels in association with disease status showed a statistically significant association between serum GP88 levels and disease progression or response to therapy while CA15-3 level was only associated to progression.
conclusionThe association of serum GP88 level with survival and disease status suggests the potential of using the serum GP88 test for monitoring disease status in patients with MBC. Measurement of serum GP88 levels in patients with MBC may have clinical value as a cost-effective adjunct to the management of patients with MBC with imaging.
