Blood and Saliva Composition in Cancer: Similarities or Differences?
Review in Current issues in molecular biology, 2026. 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
Saliva is of great interest for diagnosing and monitoring various diseases, including cancer. Saliva contains a wide range of proteins, some of which are found in blood plasma, while others are unique. Despite the obvious advantages of using saliva for diagnostics and patient monitoring, difficulties in interpreting salivary values remain. Furthermore, the extent to which salivary results correlate with blood test results remains unclear. In this review, we have collected and analyzed all currently available parallel studies of saliva and blood on the nature of changes in biochemical parameters, cytokines, growth factors, hormones, and tumor markers in cancer patients. The most contradictory and divergent changes in saliva and blood were observed when measuring biochemical parameters. Cytokines, growth factors, hormones, and tumor markers in both saliva and blood have a higher reproducibility between independent studies. It is important to consider that the causes and mechanisms behind a particular indicator in saliva may differ from those underlying the same indicators in the blood. Furthermore, these indicators may not always be directly related to cancer. We suggest that comparing identical parameters in blood and saliva is useful in the context of "pathological process routing." The paper also provides interpretations and hypotheses regarding the causes and nature of changes in saliva and blood composition in cancer.
