Salivary Sialic Acid Levels as a Biomarker for Early Detection of Oral Precancer and Oral Cancer: Systematic Review and Meta-Analysis.

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
objectiveSalivary sialic acid (SSA) has been detected as biomarker in several cancers and the level of salivary sialic acids has been proven to have a potential diagnostic value in early detection of cancer. This systematic review aims to assess Salivary Sialic Acid (SSA) levels as a biomarker for early detection of oral precancer and oral cancer. DATA SOURCES: A comprehensive Literature search was conducted in various databases such as PubMed, Scopus, Google scholar and ProQuest. Quality assessment of articles was done by Newcastle Ottawa Quality Assessment Scale.
resultsA total of 22 studies were included in the systematic review and 14 articles were included for meta-analysis. Studies showed an increase in SSA levels in both oral precancer (SMD 1.79; 95% CI 0.41-3.18), and oral cancer (SMD 11.30; 95% CI -17.04 - 39.64). Total free and protein-bound sialic acid levels were increased in oral cancer group as compared to the healthy controls. The overall standard mean difference of FSA, PBSA, TSA among oral cancer and HC (SMD 23.83; 95% CI 9.22-38.44; p=0.02) and the data revealed statistically significant differences. The results of Meta-analysis revealed statistically significant differences between SSA levels of oral cancer and healthy group.
conclusionSalivary sialic acid levels were observed to be consistently higher in oral cancer group compared to oral precancer and healthy group. However, a cut-off value of SSA levels for the early detection of oral cancer and precancer could not be established because of the limited and heterogeneous data. In order to translate the use of SSA levels into clinical practice, to utilize it as a sensitive and reliable biomarker, more standardized method of saliva processing and biochemical analysis are required with studies conducted on larger populations.
