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

Recent studies have shown that altered expression p21 is shown to associate with tumorigenesis and tumor progression. To investigate the clinicopathological significance and prognostic value of p21 in bladder cancer (BCa). A total of 48 patients with BCa were included in this study. The correlation between p21 expression and clinicopathologic features and survival was studied. Also, a meta-analysis was performed to investigate the relationship between the p21 and BCa survival. Low p21 expression was detected both in tumor tissues compared with adjacent normal tissues. The expression of p21 was closely associated with advanced pathologic TNM stage (P=0.001) and tumor grade (P=0.013). Moreover, patients with low p21 expression had shorter recurrence-free survival (P=0.016) and overall survival rates (P=0.039). Multivariate Cox regression analysis revealed that p21 low expression was an independent prognostic factor for recurrence free survival (P=0.03). Additionally, our meta-analysis. The available outcome data from six articles were examined. A meta-analysis of the HR indicated a significantly poor overall survival (OS, HR: 1.75, 95% CI: 1.38-2.21), recurrence free survival (RFS, HR: 1.83, 95% CI: 1.57-2.15), progression free survival (PFS, HR: 2.02, 95% CI: 1.48-2.75), and cancer specific survival (CSS, HR: 1.89, 95% CI: 1.53-2.33) in patients with low expression levels of p21. Our present results indicated that low p21 expression predicated tumor recurrence and poor prognosis in bladder cancer.
