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
BACKGROUND AND
objectiveThe first-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) have shown significant therapeutic effects on patients harboring sensitive EGFR mutations, while the mechanisms related to drug resistance have still remained elusive. This study aimed to indicate the relationship between the expression level of Wnt5a with therapeutic effects of first-generation EGFR-TKIs on lung adenocarcinoma patients harboring sensitive EGFR mutations.
methodsThe medical records of 75 lung adenocarcinoma patients harboring sensitive EGFR mutations, who were admitted to our hospital and received first-generation EGFR-TKIs from June 1, 2010 to December 31, 2016, were analyzed. According to the efficacy of first-generation EGFR-TKIs, patients were divided into ineffective groups (progression-free survival (PFS) <5 months) and effective groups (PFS > 26 months). Immunofluorescence staining, immunohistochemical staining and reverse transcription polymerase chain reaction (RT-PCR) methods were utilized to detect the expression level of Wnt5a in the two groups.
resultsAmong 75 patients, 36 patients were sensitive to first-generation EGFR-TKIs (effective group) and 39 patients were resistant to first-generation EGFR-TKIs (ineffective group). The location of Wnt5a was detected by immunofluorescence staining. Immunohistochemical staining demonstrated that the expression level of Wnt5a in the ineffective group was significantly higher than that in the effective group (P=0.0216). Besides, results of RT-PCR showed that the relative expression level of Wnt5a was remarkably higher in the ineffective group than that in the effective group (P=0.0135).
conclusionThe expression level of Wnt5a was found to be associated with therapeutic effects of first-generation EGFR-TKIs in lung adenocarcinoma patients harboring sensitive EGFR mutations.
