The High Presence of HCMV pp71 Proteins, Correlate with P63 Expression in Pancreatic Cancer Tumor Tissue.

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
objectiveThe purpose of this retrospective investigation was (1) to screen the existence of HCMV in pancreatic cancer tissues in relation to the histopathological grading system of such tumor tissues. (2) To evaluate the expression of the (P63) tumor suppressor gene in these tissues. (3) To find out the impact of the coexistence of (HCMV) along with the p63 on the occurring histopathological alterations.
methodsThe current retrospective cohort study included 35 paraffinized pancreatic tissues from the archives of major hospitals and numerous private histopathological laboratories from 2015 to 2020. (Twenty-five pancreatic carcinomatous tissues and 10 biopsies from seemingly normal pancreatic tissues were examined). Tissue slices from the desired tissue blocks were subjected to the immunohistochemistry (IHC) technique to detect Human Cytomegalovirus pp71 and tumor suppressor P63 proteins with aid of monoclonal primary antibodies.
resultsThe HCMV pp71 proteins were found in 92% (23 out of 25) of pancreatic tumor tissues, while it was in two (20%) of healthy pancreatic tissues. in comparison, the p63 proteins were found in 76% (19 out of 25) of tumor tissues and in four (40%) of their correlative healthy tissues.
conclusionThe increased expression of HCMV in malignant pancreatic tissue may indicate its primary or secondary role in the emergence of this type of cancer, whereupon HCMV inactivation may be useful in the treatment of this type of cancer. On the other hand, p63's high levels of expression in malignant pancreatic tumors reflect either an oppressive function or an unfortunate mutation that prevents it from functioning.
