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: Lung cancer remains the leading cause of cancer-related mortality worldwide, with non-small cell lung cancer (NSCLC) accounting for approximately 85% of cases. Accurate differentiation between adenocarcinoma (ADC) and squamous cell carcinoma (SCC) is critical for informing personalized therapies. Thyroid transcription factor-1 (TTF-1) and p40 are traditionally regarded as mutually exclusive markers of ADC and SCC, respectively. However, a subset of tumors exhibits co-expression of TTF-1 and p40, presenting diagnostic challenges and suggesting underlying biological distinctiveness. This study aimed to characterize the clinicopathological, molecular, and immunohistochemical features of NSCLCs co-expressing TTF-1 and p40, in order to clarify their biological and clinical significance. Methods: A retrospective analysis was performed on NSCLC cases diagnosed at the Central Clinical Hospital of the Medical University of Łódź between May 2021 and November 2022. Clinicopathological and survival data were collected. Tumors co-expressing TTF-1 and p40 underwent immunohistochemical evaluation and RNA/DNA-based next-generation sequencing (NGS). Results: Of 94 NSCLC cases analyzed, 18 (19.1%) demonstrated co-expression of TTF-1 and p40. These tumors were significantly more likely to exhibit solid growth patterns compared to control cases (P=0.03), but no significant difference in overall survival (OS) was observed (P=0.46). Among 17 samples subjected to NGS, genetic alterations were identified in 15 (88.2%) cases, with Conclusions: NSCLCs co-expressing TTF-1 and p40 appear to represent a biologically distinct and poorly differentiated subgroup, frequently associated with
