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

objectiveTo investigate the protein expression of matrix metalloproteinase 2 (MMP2) and its clinical significance in laryngeal cancer.

methodsA comprehensive search for the related literature published in China and other countries was conducted in a variety of databases, including MEDLINE, Embase, China Academic Journals Full-text Database, Wanfang Data and VIP Database. A total of seven case-control studies were included in the final systematic assessment. A meta-analysis software program was used to statistically analyze the raw data from each study for the calculation of the pooled odds ratio (OR) and 95% confidence interval (95% CI).

resultsThe meta-analysis indicated that, compared with normal laryngeal tissue, the MMP2 protein was highly expressed in the laryngeal cancer tissue [OR=21.67; 95% CI: 11.61-40.43; P<0.001]. Compared with highly differentiated laryngeal cancer, the MMP2 protein expression level was higher in the moderately and poorly differentiated laryngeal cancers [OR=0.25; 95% CI: 0.13-0.46; P<0.001]. Compared with laryngeal cancers without lymph node metastasis, the laryngeal cancers with lymph node metastasis exhibited a greatly elevated MMP2 protein expression [OR=0.25; 95% CI: 0.14-0.46; P<0.001].

conclusionHigh protein expression levels of MMP2 may play an important role in the tumorigenesis, progression and prognosis of laryngeal cancer.
