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 prognostic impact of different distant metastases pattern in bladder cancer is unexplored still now. The aim of this study is to investigate the impact of different distant metastases pattern on the survival of patients with stage IV bladder cancers.

methodsA SEER analysis was performed and the overall survival was calculated by the Kaplan-Meier method. Multivariable Cox regression models were used to further analyze survival outcome and other prognostic factors.

resultsA total of 90,382 eligible cases were retrieved in the Surveillance, Epidemiology, and End Results database. Among these patients, stage of IV bladder cancer accounted for 7.03% (6354/90382) at initial diagnosis. Patients who suffered metastasis occupied 35.51% (2256/6354). Comparing with other three single metastases, the patients with liver metastasis exhibited worst OS whose mean of survival was 7.118 months. Multivariate analysis with Cox hazard regression model showed that metastatic site was an independent prognostic factor of OS in patients with single metastasis (P < 0.05). The results of univariate survival analysis showed that metastatic pattern, sex, age, race, tumor stage, N-classification, differentiated grade, histological type, chemotherapy, radiotherapy and insurance status were not significantly correlated with overall survival of patients with two or three metastatic sites (all, P > 0.05).

conclusionsBone was the most common site of single metastasis for bladder cancers. Patients with liver metastasis had worse survival outcome comparing with other three distant metastases. Knowledge of these differences in metastatic patterns might help to better guide pre-treatment evaluation of bladder cancer and make determination regarding curative-intent interventions.
