Low expression of BTN3A3 indicates poor prognosis and promotes cell proliferation, migration and invasion in non-small cell lung cancer.
Article in Annals of translational medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundThe butyrophilin (BTN) family has many members with diverse functions related to immunomodulation, initiation and progression of tumors. BTN3A3 belongs to the BTN family, and exploring its expression and correlation with the prognosis of non-small cell lung cancer (NSCLC) patients has great clinical significance.
methodsClinical specimens were used to detect BTN3A3 expression. Small interfering RNA (siRNA) was used to knock down BTN3A3 and analyze the proliferative, migratory and invading ability of the transfected NSCLC cells. Multiplex immunofluorescence staining was used to detect the expression of BTN3A3 protein in the tumor microenvironment (TME). We analyzed the relationship between the expression of BTN3A3 and the clinicopathological features and prognosis of NSCLC patients.
resultsThe expression of BTN3A3 in NSCLC tissues was significantly lower than in adjacent tissues, and patients with low expression of BTN3A3 had late clinical stages and lower degree of tumor differentiation. Knocking down BTN3A3 promoted the proliferation, migration and invasion of NSCLC. In the TME, the density of BTN3A3+ tumor cells positively correlated with the density of CD8+ T cells, and the patients with low expression of BTN3A3 had poor overall survival (OS).
conclusionsChanges in the BTN3A3 expression level may play a potential key role in the carcinogenesis and development of NSCLC. Patients with low expression of BTN3A3 showed a more aggressive and invasive phenotype and a lower level of CD8+ T-cell infiltration, which may be an important factor affecting the OS of NSCLC patients.
