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
objectivesTo screen genes related to the prognosis of oral squamous cell carcinoma (OSCC), and to explore its role and mechanism in the occurrence and development of OSCC.
methodsThe data and the biological information in 330 OSCC tumor samples with head and neck squamous cell carcinoma (HNSCC) (OSCC group) and 37 normal samples (normal sample group) were screened and included, which came from the cancer genome atlas (TCGA) database. The differentially expressed genes were screened out by biological information analysis between the 2 groups. Furthermore, according to the tumor T grade (T1+T2 group: 114 cases, T3+T4 group: 216 cases), metastasis (positive group: 163 cases, negative group: 167 cases) and pathological grade (G1+G2 group: 244 cases, G3 +G4 group: 86 cases), the samples were divided into different groups respectively, and the differential genes were obtained separately, then the intersections of the differential expressed genes related to the prognosis of OSCC were screened. The different gene with the largest different multiples [hyaluronan mediated motility receptor (HMMR)] was selected for the next step in order to explore the relationship between HMMR and clinical grading (Stage I+II group: 69 cases, Stage III +IV group: 261 cases), as well as the relationship between T grade, metastasis and pathological grade. According to the median value of HMMR expression, the samples were divided into a high expression group and a low expression group (high expression group: 165 cases, low expression group: 165 cases); Kaplan-Meier survival analysis was used to explore the relationship between HMMR expression and prognosis. Tumor tissue specimens and corresponding normal oral mucosal tissue specimens in 50 OSCC patients, who underwent surgery in the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from January 2014 to January 2016, were collected. Real-time RT-PCR and Western blotting and immunohistochemistry were used to verify the bioinformatics analysis results. Kaplan-Meier survival analysis was used to examine the relationship between the positive and negative expression of HMMR immunohistochemical staining (positive group: 32 cases, negative group: 18 cases) and prognostic related factors, and Cox regression analysis model was used to explore the prognostic risk factors of OSCC. The cell proliferation experiment and the cell scratch experiment were used to evaluate the effect of down-regulation of HMMR on the proliferation and migration of OSCC cells.
resultsHMMR was highly expressed in OSCC tissues. Compared with the low HMMR expression group, the prognostic related factors in the HMMR high expression group was significantly lower, with significant difference (all
conclusionsHMMR, as a proto-oncogene of OSCC, can promote the occurrence and development of OSCC, and it may be used as a potential early diagnostic marker and a new target for therapy.
