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: This study aims to investigate whether the invasive staging of aortopulmonary window lymph nodes could be omitted in the presence of a suspected isolated metastasis in the aortopulmonary window lymph node on positron emission tomography/computed tomography. Methods: Between January 2010 and January 2016, a total of 67 patients (54 males, 13 females; mean age: 59.9±8.7 years; range, 44 to 76 years) with metastatic left upper lobe tumors to aortopulmonary window lymph nodes were retrospectively analyzed. According to positron emission tomography/computed tomography findings in clinical staging, the patients were classified as positive (+) (n=33) and negative (-) (n=34) groups. Results: There was a statistically significant difference between the two groups in terms of sex distribution, lymph node diameter on computed tomography, maximum standardized uptake value of aortopulmonary window lymph nodes, and tumor diameter (p<0.001 for all). A trend toward significance was found to be in pT status, LN #6 metastases, and pathological stage between the two groups (p=0.067). The five-year overall survival rate for all patients was 42.4% and there was no significant difference between the groups (p=0.896). The maximum standardized uptake value of the aortopulmonary window lymph nodes was a poor prognostic factor for survival (area under the curve=0.533, 95% confidence interval: 0.407-0.675, p=0.648). Conclusion: Invasive staging of aortopulmonary window lymph nodes can be omitted in patients with isolated suspected metastasis to aortopulmonary window lymph nodes in non-small cell lung cancer of the left upper lobe.
