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

backgroundInhibitors of programmed cell death-1 (PD-1) and its ligand (PD-L1) have represented a novel approach for the management of advanced non-small cell lung cancer (NSCLC). In this study, we aimed to estimate five anti-PD-1/L1 agents (nivolumab, pembrolizumab, atezolizumab, durvalumab, and avelumab) using network meta-analyses (NMAs) and the Bayesian method to provide suggestions for advanced NSCLC treatments.

methodsWe searched PubMed, Web of Science, Embase, and the Wiley Online Library for eligible studies published up to March 2020. Both pairwise analyses and NMAs were conducted with clinical outcomes, including overall survival (OS), progression-free survival (PFS), objective response rate, and the incidences of adverse events. Results were presented in several patient populations according to treatment lines and PD-L1 status.

resultsNineteen randomized clinical trials (RCTs) involving 11,456 patients were included in our study. PD-1/L1 inhibitors showed significant benefits over chemotherapies in OS regardless of tumor PD-L1 status [first-line settings: OS =0.85, 95% CI (0.77, 0.94), I

conclusionsThe combination of pembrolizumab with chemotherapy is suitable for advanced NSCLC patients who have not received any systematic treatments before, and pembrolizumab monotherapy should also be considered, especially for patients with highly-expressed PD-L1 (≥50%). Nivolumab is the best option for patients with advanced NSCLC whose tumors have progressed following chemotherapies or combined modalities of treatments including chemotherapy. However, our results need to be further validated in future head-to-head clinical trials.
