First-line PD-1/PD-L1 inhibitor plus chemotherapy vs chemotherapy alone for negative or < 1% PD-L1-expressing metastatic non-small-cell lung cancers.

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
aimsSingle-agent anti-PD-1/PD-L1 clinical efficacy against < 1% PD-L1-expressing non-small-cell lung cancers (NSCLCs) is controversial.
methodsThis meta-analysis examined randomized-trial data comparing first-line PD-1/PD-L1-inhibitor + chemotherapy (CT) vs CT alone for advanced < 1% PD-L1 NSCLCs. Outcome measures included overall survival (OS), progression-free survival (PFS) and objective response rate (ORR).
resultsIMpower (atezolizumab + CT), Keynote (pembrolizumab + CT) and CheckMate (nivolumab + CT) trials included 2037 NSCLCs (1246 PD-L1-negative; 791 < 1% PD-L1 expression). Anti-PD-1/PD-L1 + CT was significantly associated (hazard ratio [95% confidence interval]) with prolonged OS (0.75 [0.63-0.89]; p = 0.0008) and PFS (0.72 [0.65-0.80]; p < 0.0001), and higher ORR (odds ratio 2.06 [1.50-2.83]; p < 0.0001).
conclusionsFirst-line anti-PD-1/PD-L1 + CT combination appears superior to CT alone for advanced, < 1% PD-L1-expressing NSCLCs for OS, PFS and ORR.
