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
Introduction Recently, the expression of metallophosphoesterase-domain-containing protein 2 (MPPED2) was identified in cervical cancer. However, its precise role and correlation with other tumor suppressor proteins, such as p16INK4A, is not well studied in high-risk human papillomavirus (HPV) integrated human cervical carcinoma. Hence, in the present study, we try to see the expression of MPPED2 in human cervical carcinoma and its correlation with age and p16INK4A protein expression level. Methods The prospective study consists of 200 samples of 150 known cervical carcinoma and 50 controls. Histopathological evaluation, immunohistochemical staining, and semi-quantitative scoring of the intensity of proteins were performed. Statistical analysis was performed with the Shapiro-Wilk test, Spearman's rho correlation sig. (two-tailed), and Student's t-test. Results The data show that among the 150 cases, 136 (68.0%) cervical carcinoma tissues express the presence of high-risk HPV viral genome integration in the host cell. The expression of p16INK4A protein is higher in those tissues identified with high-risk HPV viral genomes. In contrast, the expression of MPPED2 protein is lesser or absent in those cervical tissues that have the higher expression of p16INK4A protein and vice versa. There is a significant correlation (p=0.000) between age and p16INK4A protein expression but not with MPPED2. A significant linear correlation (p=0.000) is found between the p16INK4A and MPPED2 proteins. Conclusion It may support the therapeutic application of MPPED2 protein to prevent cervical carcinoma progression in the near future.
