1 · What the graph read from it

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.

2 · The registry

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 PER1 circadian-clock gene plays an important role in the regulation of many normal physiological rhythms in vivo. It has been revealed recently that abnormal expression of PER1 correlates closely with the occurrence and development of many cancers. However, the expression and significance of PER1 in oral squamous cell carcinoma (OSCC) remains unknown. The purpose of the present study was to investigate the direct links between aberrant PER1 expression and clinicopathological features of OSCC.

methodsPER1 expression in cancerous and adjacent noncancerous tissues from 41 patients with OSCC was detected by immunohistochemical staining and real-time reverse transcriptase polymerase chain reaction, and correlations were sought with clinicopathological features in patients.

resultsExpression of PER1 mRNA and protein in OSCC was significantly reduced compared with that in adjacent noncancerous tissue (P < 0.05). Expression of PER1 protein in oral phase III-IV SCC specimens was significantly lower than that in phase I-II specimens (P < 0.05), and stage T(1)-T(2) patients expressed significantly higher levels of PER1 protein than T(3)-T(4) patients (P < 0.05). Expression of PER1 in patients without lymph node metastasis was significantly higher than that in those with lymph node metastasis (P < 0.05). PER1 protein expression showed no significant correlation with patient gender and age, or with degree of tumor cell differentiation (P > 0.05).

conclusionChanges in PER1 expression may play an important role in the development, invasion, and metastasis of OSCC, and may also provide novel ideas and methods for investigation of the occurrence, development, and targeted treatment OSCC.
