The prognostic implications of podoplanin in cancer-associated fibroblasts and PD-L1 expression in high-grade neuroendocrine carcinoma of the lung.

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
objectivesPodoplanin (PDPN) expression in cancer-associated fibroblasts (CAFs) (CAF-PDPN) is considered a poor prognostic factor in nonsmall cell lung cancer, but little is known about its clinical significance in high-grade neuroendocrine carcinoma of the lung (HGNEC). This study examines the association between CAF-PDPN and stromal programmed death-ligand 1 (PD-L1) expression and the prognostic implications of CAF-PDPN and PD-L1 expression status in surgically resected HGNEC patients.
methodsImmunohistochemical analyses were performed on 121 resected HGNEC specimens using antibodies against PDPN and PD-L1. Correlations between CAF-PDPN, stromal PD-L1 expression, and clinicopathologic features and their implications for survival were analyzed statistically.
resultsThere were substantially more large-cell neuroendocrine carcinomas in the stromal PD-L1-positive group and more vascular invasion in the tumoral PD-L1-positive group. PDPN expression in CAF was moderately correlated with stromal PD-L1 expression (ρ = 0.567, p < 0.001). In a survival analysis combining CAF-PDPN and stromal PD-L1 status, the 5-year RFS rates for Group A: CAF-PDPN (+)/stromal PD-L1 (+), Group B: CAF-PDPN (+)/stromal PD-L1 (-), Group C: CAF-PDPN (-)/stromal PD-L1 (+), and Group D: CAF-PDPN (-)/stromal PD-L1 (-) were 62.0%, 46.8%, 17.5%, and 20.2%, respectively, with corresponding 5-year OS rates of 76.6%, 69.2%, 27.0%, and 25.3%. The log-rank test showed statistically significant differences among the groups in RFS (p < 0.001) and OS (p < 0.001).
conclusionsThere is a correlation between CAF-PDPN and tumoral/stromal PD-L1 expression, and positive status for either CAF-PDPN or stromal PD-L1 expression could be an independent favorable prognostic factor in surgically resected HGNEC patients.
