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
backgroundTrkC, a member of neurotrophin receptor family, functions not only as an oncogene, but also act as a tumor suppressor via a manner of dependence receptor in human malignant tumors. Little is known on the action of TrkC for the clinical prognosis and the progression of breast cancer according to the availability of its ligand NT-3. We sought to investigate the prognostic relevance of NT-3-TrkC axis in breast cancer and estimate its role during the process of breast cancer progression.
methods236 cases of invasive ductal carcinoma (IDC), 60 pure ductal carcinoma in situ (DCIS) and 30 normal breast tissue (NBT) between 2004 and 2005 were included in the study. Spearman's rank correlation test was used to analyze the association of NT-3-TrkC expression and breast cancer progression. The Kaplan-Meier method and Cox proportional hazards model were performed to identify the relevant prognostic factors.
results50.4% IDC tumors displayed absent or low TrkC expression, while 49.6% was high TrkC expression. TrkC expression was negatively associated with lymph node metastasis (P = 0.029) and tumor proliferation (P = 0.015). Patients with lower TrkC expressing tumors had a higher risk of recurrence (odds ratio, 0.401; 95% confidence interval, 0.207-0.778; P = 0.007). The layered analysis indicated that patients with high TrkC expression tumors had a favor disease-free survival whether NT-3 and TrkC were co-expressed or solitarily expressed in the tumor (P = 0.000). NT-3 was demonstrated to be not a predictor of IDC patients' prognosis. But NT-3 expression was inversely correlated with the progression of breast cancer (r = -0.341, P = 0.000), since more IDC tumors showed high NT-3 expression than DCIS tumors (51.7% vs. 25.9%), while no NBT showed high NT-3 expression, as well.
conclusionThe study indicates TrkC expression reduces tumor relapse independent of NT-3 availability in the IDC. Elevated NT-3 expression contributes to the progression of breast cancer.
