A Study of Cytokeratin-7 Expression and Clinicopathological Correlation in Dysplasia and Squamous Cell Carcinoma of the Cervix.
Article in Asian Pacific journal of cancer prevention : APJCP, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesCytokeratin (CK) proteins play a vital role in cancer diagnosis, of which,CK-7 is a prominent marker of squamocolumnar junction cells corresponding to the the initiating site of cervical cancer.The current study is aimed to evaluate the expression pattern of CK-7 and to corelate with the clinicopathological features in patients with cervical dysplasia and invasive squamous cell carcinoma. METHODOLOGY: The hysterectomy and biopsy specimens from women with cervical dysplasia (n=60) and carcinoma (n=60) were evaluated histopathologically and processed for immunohistochemistry (IHC) staining to assess for CK-7 expression. The relationship between CK-7 expression and tumor characteristics like histological type of cervical intraepithelial neoplasia (CIN), tumor type and grade was evaluated. Data was analyzed using the Chi-square test ,wherein the p value ≤ 0.05 were taken for statistical significance.
resultsPositive CK-7 expression was observed in 25 (41.67%) dysplasia and in 34 (56.67%) carcinoma cases. Majority of the cases were CIN III (n=31, 51.67%), large cell non-keratinizing tumor type (n=54, 90%) and moderately differentiated grade of tumor (n=52, 86.67%), out of which 18 (58.1%), 34 (62.96%) and 30 (57.69%) cases were CK-7 positive, respectively. The difference in clinical diagnosis and tumor characteristics over CK-7 expression was significant (p<0.05). The pattern of CK-7 expression in dysplasia and carcinoma cases were diffuse in 23 (38.33%) and 31 (51.67%) respectively and patchy in 2 (3.33%) and 3 (5%) of them, respectively.
conclusionSignificant positive CK-7 expression in cervical dysplasia and carcinoma indicates a good clinical course and its role as a useful predictable marker for cancer progression.
