nm23 protein expression in metastatic and non-metastatic tongue squamous cell carcinoma.
Article in Brazilian journal of otorhinolaryngology. 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
unlabelledOral squamous cells carcinoma (OSCC) shows unfavorable prognosis due to its invasion potential around the neighboring tissues and the elevated incidence of metastasis.
aimthe present paper aims at analyzing the immunohistochemical expression of the nm23 protein in metastatic and non-metastatic SCCs of tongue.
methodsthe immuno-expression to the nm23-hl protein was diagnosed in 35 tongue SCC (15 of which exhibiting metastasis). Nm23-hl immuno-scores were assigned as follow: score 0 = absent, 1 = focal and 2 = diffuse expression.
resultsThe Fisher's exact test was performed and there was no statistical difference between the nm23-hl immuno-scores and the tongue SCCs studied cases (p=0.365), although 66.7% of metastatic cases presented negative nm23-hl expression.
conclusionsProtein nm23 was not associated with a positiveness for tongue SCC without metastasis. Thus, several others factors inherent to host and malignancy can be associated with the mechanisms that suppress the metastatic process in this disease.
