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

Osteosarcoma is the most common primary malignant bone tumor of childhood. Vascular endothelial growth factor (VEGF) expression has been implicated in tumor development and progression of osteosarcoma, but previous studies investigating the impact of VEGF expression on overall survival in patients with osteosarcoma report conflicting findings. A meta-analysis of published studies was performed. The pooled hazard ratio (HR) with its 95% confidence interval (95% CI) was used to assess the impact of VEGF expression on overall survival in patients with osteosarcoma. Nine studies with a total of 432 osteosarcoma patients were included into this meta-analysis. There was no between-study heterogeneity among those nine studies (I (2) = 0.0%). Overall, high VEGF expression was obviously associated with poorer overall survival (HR = 1.68, 95% CI 1.33-2.12, P < 0.001). Sensitivity analysis performed by excluding single study in turns showed the pooled estimate was stable. Egger's test also did not suggest evidence for publication bias (P = 0.216). Therefore, this meta-analysis suggests that VEGF expression has an important impact on overall survival in patients with osteosarcoma and high VEGF expression is associated with poorer overall survival.
