Immunocytochemical Evaluation of TTF-1, Napsin-A, and p-63 for Subtyping of Non-Small Cell Lung Carcinoma and Clinicopathological Correlation.
Article in Journal of cytology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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: Carcinoma of lung is the most common cause of cancer-associated mortality worldwide. About 70% of lung cancer cases are unresectable and present in advanced stages. So, cytology and small core needle biopsy specimen are available for diagnostic as well as prognostication workup. Subtyping of non-small cell lung cancer (NSCLC) is essential for the treatment and further workup study. For this, immunocytochemistry (ICC) plays a crucial role that helps in early diagnosis. Subtyping of NSCLC from cytology samples using ICC markers like TTF-1, Napsin-A, and p63 and their clinicopathological correlation are the aims of the study. Materials and Methods: This ambispective study was conducted in the pathology department of a tertiary care hospital of eastern India for a 2-year period from 2018 to 2020. In our study, 46 cytologically diagnosed cases of NSCLC were included. Subtyping was done by cytomorphology and correlated with ICC expression, histopathology, and clinicopathological parameters. Results: In our study, adenocarcinoma (ADC) was the most common (32.61%) cancer. Most cases of ADC showed positive expression of TTF-1 and Napsin-A, and p63 was positive in most cases of squamous cell carcinoma (SCC). Concordance with cytomorphology and ICC was 87.50% and 81.81% with ADC and SCC, respectively. Cyto-ICC-histo concordance was observed in 85.51% of ADC and 66.66% of SCC cases. Sensitivity was 100%, 93.1%, and 100% for TTF-1, Napsin-A, and p63, respectively. Specificity of both TTF-1 and Napsin-A was 88.2% and for p63 was 93.8%. Conclusion: In small biopsy along with cytology samples, ICC is cost-effective and plays an important role in early diagnosis along with management of NSCLC.
