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
objectiveScreening of colorectal cancer (CRC) is important for the early detection. CRC is relating to aging and immuno-senescence. One such senescent marker is p16INK4A expression in immune cells. The objective of the study is to investigate the protein expression of p16INK4A in peripheral white blood cells as a screening marker for colorectal cancer.
methodsA case-control studies were conducted. Cases were patients with colorectal cancer and controls were matched with cases based on age and sex. Peripheral blood was collected from patients and controls and the protein p16INK4A was measured with immunofluorescent techniques. The p16INK4A levels from cases and controls were evaluated using ROC analysis to be used as a screening marker in CRC patients. Mean fluorescent intensity of p16INK4A of cases and controls were analyzed in CD45+, CD3+ or CD14+ cells. The p16INK4A levels of cases were also correlated with clinical data.
resultStatistically significant increased expression of p16INK4A levels were found in cases compared to controls. p16INK4A in peripheral immune cells had 78% sensitivity and 71% specificity which can possibly be used as a diagnosis tool for colorectal cancer. P16INK4A-positive cell percentage and mean florescent intensity were significantly higher in CD45+ cells, CD3 positive cells and CD14 positive cells. No significant correlation was observed with the clinical data and p16INK4A level of CRC patients.
conclusionThe significant increase of p16 INK4A expression level in peripheral immune cells represents potential for use as a CRC screening marker.
