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.
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
backgroundRecently, several high-quality clinical randomized controlled trials (RCTs) have identified that cyclin-dependent kinases (CDKs) 4/6 inhibitors obtained a great safety and efficacy, which can be consequently applied as a combination therapy with letrozole or fulvestrant for women who had advanced breast cancer and progressed while receiving endocrine therapy. In this systemic review, we performed a meta-analysis to explore whether CDK4/6 inhibitors had a significantly benefit to treating hormone receptor-positive (HR-positive)/human epidermal growth factor receptor 2 negative (HER2-negative) advanced breast cancer.
methodsThe data for meta-analysis were collected from MEDLINE, EMBASE, and Cochrane Library from January 1980 to December 2017, and eventually 3182 patients from 6 RCTs were included.
resultsThe result showed the CDK4/6 inhibitor group had a longer progression-free survival (PFS) (hazard ratio = 0.51; 95% confidence interval [CI], 0.46-0.57, P < .00001), a better objective response (risk rate = 1.53; 95% CI, 1.35-1.74, P < .00001), as well as a better clinical benefit response (risk rate = 1.29; 95% CI, 1.13-1.47, P = .0001). Besides, subgroup analyses of PFS according to stratification factors and other baseline characteristics confirmed a great performance of CDK4/6 inhibitors across the all subgroups. And sensitive analysis showed that all outcomes were stable except Finn 2014 trail.
conclusionCDK4/6 inhibitors can significantly prolong the PFS and improve the objective response and clinical benefit response among the patients with HR-positive/ HER2-negative advanced breast cancer.
