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
Accumulating studies explored the clinicopathologic and prognostic value of programmed death ligand-1 (PD-L1) in non-small cell lung cancer (NSCLC), but the results were controversial. We therefore conducted a meta-analysis to evaluate the predictive role of PD-L1 in NSCLC patients. We systematically collected relevant studies from PubMed, Embase, Web of Science and China National Knowledge Infrastructure. The pooled hazard ratios (HRs) with 95% confidence intervals (CIs) for overall survival (OS), and odd ratios (ORs) with 95% CIs for clinicopathologic factors were calculated. A total of 15 studies involving 3605 patients were included in this meta-analysis. The results showed no prognostic role of PD-L1 in the whole patients (HR=1.60, 95% CI: 0.88-2.89, P=0.123). Subgroup analysis showed that PD-L1 was associated with decreased OS in Asian patients (HR=2.00, 95% CI: 1.55-2.57, P<0.001). Among all the clinicopathologic factors, PD-L1 overexpression was significantly in relevance with poor tumor cell differentiation (HR=1.84, 95% CI: 1.49-2.28, P<0.001), late stage (HR=1.21, 95% CI: 1.02-1.43, P=0.026) and anaplastic lymphoma kinase (ALK) translocation (HR=2.63, 95% CI: 1.08-6.40, P=0.034), but not with other factors. In conclusion, our meta-analysis demonstrated that PD-L1 has a prognostic role in Asian patients with NSCLC.
