Immunohistochemical Expression of Basement Membrane Laminin in Histological Grades of Oral Squamous Cell Carcinoma: A Semiquantitative Analysis.
Article in Journal of pharmacy & bioallied sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Oral squamous cell carcinoma (OSCC) is a prevalent malignancy characterized by varying histological grades. Basement membrane laminin expression plays a crucial role in tumor invasion and progression. This study aimed to assess the immunohistochemical expression of basement membrane laminin in different histological grades of OSCC. Materials and Methods: Archival tissue samples of OSCC from 60 patients were categorized into well-differentiated, moderately differentiated, and poorly differentiated grades. Immunohistochemistry was performed using anti-laminin antibodies, and staining intensity was semiquantitatively analyzed using a scoring system. Results: The immunohistochemical analysis revealed varying levels of laminin expression across different histological grades of OSCC. Well-differentiated tumors showed an average staining intensity score of 7.2 (SD ± 1.5), moderately differentiated tumors had a score of 5.8 (SD ± 1.2), and poorly differentiated tumors exhibited a score of 4.3 (SD ± 0.9). Statistical analysis indicated a significant difference in laminin expression between histological grades ( Conclusion: Our findings demonstrate a progressive decrease in basement membrane laminin expression with an increasing histological grade of OSCC. This suggests that laminin may be a potential biomarker for assessing tumor aggressiveness and prognosis in oral squamous cell carcinoma.
