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
objectiveTo explore the prognosis factors that influence the postoperative survival rate in patients with malignant solitary pulmonary nodules and to provide a reference for the prognosis risk stratification of early lung cancer patients.
methodsIn this study, we retrospectively reviewed 172 patients who were admitted to Peking University First Hospital from April 2006 to December 2013. All cases were radiologically defined as solitary pulmonary nodule and were pathologically confirmed to be stage Ia non-small cell lung cancer after surgical procedure. The patients' clinical and follow-up data were summarized and analyzed. The relevance between survival time and factors that may affect patients' prognosis was evaluated, which included gender, age, clinical symptoms, smoking history, comorbidity index, tumor biomarkers, nodule type, type of surgery, nodule location, nodule histopathological type, nodule size, histopathological differentiation grade, proliferating cell nuclear antigen Ki-67 expression level and epidermal growth factor receptor (EGFR) gene mutation. Kaplan-Meier survival analysis, Cox univariant and multivariant regression analysis were conducted to evaluate the factors affecting prognosis.
resultsThe 3-year overall survival rate of the atients with malignant solitary pulmonary nodules was 93.6%, and the 5-year overall survival rate was 89.8%. KaplanMeier survival analysis and Cox univariant regression analysis showed that the overall survival rate of the male patients was significantly lower than that of the female patients. In addition, the elderly patients with histopathology characterized as high Ki-67 proliferation index were also associated with the worse overall survival (P<0.05). Cox multivariant regression analysis demonstrated that age more than 65 years as well as the high Ki-67 expression level were independent risk factors for overall survival in patients with malignant solitary pulmonary nodules (age: P=0.023, HR=3.531, 95%CI 1.190-10.472; Ki-67: P=0.004, HR=1.021, 95%CI 1.007-1.035).
conclusionFor patients with malignant solitary pulmonary nodules, with pathological defined as stage Ia non-small cell lung cancer, age, gender and Ki-67 expression levels might be important prognostic factors. Comprehensive consideration of Ki-67 proliferation index and clinical pathological features may help to stratify the prognosis more accurately and guide the selection of appropriate therapeutic strategies, which needs to be verified by multi-center studies.
