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

backgroundAntiangiogenesis therapy has been demonstrated to prolong the free survival with tolerable toxicity. However the efficacy of these drugs in overall survival (OS) remains controversial. This study was designed to assess the overall performance of antiangiogenesis therapy in improving the survival of ovary cancer (OC) patients.

methodsElectronic database of PubMed, Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials were searched to identify relevant clinical randomized control trial (RCTs) assessing the therapeutic value of antiangiogenesis therapy in OC patients during 2011 to 2017. Additionally, abstracts of annual meetings were also conducted. Only English articles were considered. Progression free survival (PFS), OS, and objective response rate (ORR) were obtained from eligible RCTs. The HRs for time-to-event variables and ORs for dichotomous outcomes with their 95% CIs were used for this meta-analysis. All the statistical analyses were carried out by Stata 11.0 software using a fixed or random-models according to heterogeneity.

resultsA total of 15 RCTs including 9359 patients were recruited into this meta-analysis. Addition of antiangiogenic agents improved PFS (HR = 0.71, 95% CI 0.62-0.81, P < .001), OS (HR = 0.92, 95% CI 0.86-0.98, P = .008) and ORR (OR = 1.74, 95% CI 1.27-2.39, P = .001) compared to placebo or chemotherapy alone in overall analysis. Antiangiogenic agents prolonged both PFS (HR = 0.58, 95% CI 0.52-0.65, P = .000) and OS (HR=0.84, 95% CI 0.76-0.92, P = .000) in recurrent settings but only PFS in primary settings (HR = 0.88, 95% CI 0.79-0.98, P = .020), longer PFS and OS in both platinum-sensitive recurrent patients (HR = 0.56, 95% CI 0.48-0.64, P = .000, PFS; HR = 0.86, 95% CI 0.76-0.98, P = .027, OS) as well as platinum-resistant recurrent cases (HR = 0.54, 95% CI 0.41-0.71, P = .000, PFS; HR = 0.84, 95% CI 0.71-0.98, P = .029, OS). Throughout therapy improved PFS (HR = 0.66, 95% CI 0.57-0.76, P < .001) and OS (HR = 0.89, 95% CI 0.83-0.96, P = .001). However the maintenance therapy of antiangiogenic agents was irrelevant to a longer PFS or OS.

conclusionBased on the available studies, antiangiogenic agents play an important role in the survival of OC patients. More randomized controlled trials are needed to reach more convinced conclusion.
