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
The prognostic value of phosphatidylinositol-4, 5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) in patients with esophageal squamous cell carcinoma (ESCC) is controversial. We aimed to investigate the prognostic significance of PIK3CA mutation in patients with ESCC. EMBASE, PubMed, and Web of Science databases were systematically searched from inception through Oct. 3, 2016. The hazard ratios (HRs) and 95% confidence intervals (CI) were calculated using a random effects model for overall survival (OS) and disease-free survival (DFS). Seven studies enrolling 1505 patients were eligible for inclusion of the current meta-analysis. Results revealed that PIK3CA mutation was not significantly associated with OS (HR: 0.90, 95% CI: 0.63-1.30, P=0.591), with a significant heterogeneity (I
