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.

Abstract

backgroundSeveral clinical trials have reported that therapies targeting programmed death-1 (PD1) and its ligand (PD-L1) improve patient outcomes, while tumor response has been related to PD-L1 expression.

objectiveTo investigate the prognostic role of PD-L1 expression in patients affected by renal cell carcinoma (RCC).

methodsMEDLINE/PubMed, the Cochrane Library, and ASCO University were searched for studies investigating the prognostic role of PD-L1 expression in RCC. Data extraction was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.

resultsSix studies and 1323 cases were included in the final analysis. PD-L1 was expressed in 24.2 % of clear cell tumors compared to 10.9 % of non-clear cell tumors (p = 0.002). In the overall population, a higher level of PD-L1 expression increased the risk of death by 81 % (HR; 1.81, 95 % CI 1.31-2.49; p < 0.001). When the analysis was restricted to cases evaluated by immunohistochemistry alone, the higher expression of PD-L1 more than doubled the risk of death (HR; 2.05, 95 % CI 1.38-3.05; p < 0.001). In clear cell histology, higher PD-L1 expression increased the risk of death by 53 % (HR; 1.53, 95 % CI 1.27-1.84; p < 0.001), while in metastatic patients, the evaluation of PD-L1 expression on primary tumors revealed that it retains its prognostic role (HR; 1.45, 95 % CI 1.08-1.93; p = 0.01). LIMITATIONS: Significant heterogeneity has been identified among the included studies. As a consequence, cautious interpretation of the results is recommended.

conclusionThis meta-analysis indicates that a higher level of PD-L1 expression is a negative prognostic factor in RCC. Its validation as an independent prognostic factor compared to other traditionally used clinical parameters in localized or advanced disease is recommended.
