1 · What the graph read from it

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.

2 · The registry

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: A hormonal role in the development of non-small cell lung cancer (NSCLC) has been well documented, and the classic estrogen receptors (ERs)-ERα and ERβ have been extensively investigated over the past decade. The expression of ERβ was found to be high and display biological activity in NSCLC, but anti-estrogen therapy targeting this receptor has shown limited efficacy for the disease. The third estrogen receptor, G protein-coupled estrogen receptor 1 (GPER1/GPR30), was recently found to be highly expressed in NSCLC. Herein, we aimed to investigate the expression profile of GPER1 and correlate it with clinicopathological factors as well as postoperative prognosis in NSCLC. Methods: We examined GPER1 and ERβ expression using immunohistochemistry among 183 NSCLC cases, including 132 lung adenocarcinoma (LUAD) with identified epidermal growth factor receptor (EGFR) mutation status and 51 squamous cell carcinoma (SCC) patients. We then conducted correlation analysis between the expression of GPER1 and clinicopathological factors and patients' postoperative prognosis. Results: Positive expression of GPER1 was categorized into 2 main classes: nuclei-GPER1 (nGPER1) and concurrent nuclei-and cytoplasm-GPER1 (n/cGPER1), according to its subcellular localization. The LUAD with wild-type EGFR (wt-EGFR) had a higher frequency of n/cGPER1 (50%) but a lower frequency of nGPER1 (31%) when compared with those with mutated EGFR (n/cGPER1: 31%, nGPER1: 41%, respectively). The expression of GPER1, regardless of subcellular localization, was positively correlated with tumor stage and lymph node metastasis. The median recurrence-free survival (mRFS) and overall survival (OS) were significantly worse in participants with n/cGPER1 expression than in those with nGPER1 or without GPER1 expression. Conclusions: This study revealed that GPER1 is aberrantly highly expressed and presents a unique GPER1 expression profile in NSCLC. The n/cGPER1 expression was significantly associated with EGFR mutation status, tumor stage, lymph node metastasis, and poor postoperative prognosis in NSCLC.
