Immunotherapy combined with chemotherapy versus chemotherapy alone as the first-line treatment of PD-L1-negative and driver-gene-negative advanced nonsquamous non-small-cell lung cancer: An updated systematic review and meta-analysis.

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
backgroundThis meta-analysis aimed to compare the efficacy of immunotherapy combined with chemotherapy versus chemotherapy alone as the first-line therapy for patients with programmed death ligand-1 (PD-L1)-negative and driver-gene-negative advanced nonsquamous non-small-cell lung cancer (NSCLC). PATIENTS AND
methodsEligible randomized trials were identified following the systematic search of PubMed, Cochrane Library, Embase, Web of Science, Wanfang Data, and China Knowledge Resource Integrated Database from January 2000 to June 2022.
resultsSeven trials involving 1132 patients with PD-L1-negative and driver-gene-negative advanced nonsquamous NSCLC were included. Immunotherapy combined with chemotherapy showed significantly superior objective response rate (ORR) compared with chemotherapy alone (odds ratio 2.81, 95% confidence interval [CI] 1.69-4.65). Immunotherapy combined with chemotherapy also significantly prolonged the progression-free survival (PFS) (hazard ratio [HR] 0.63, 95% CI 0.55-0.74, p < 0.001) and overall survival (OS) (HR 0.68, 95% CI 0.56-0.82, p < 0.001) of patients with PD-L1-negative and driver-gene-negative advanced nonsquamous NSCLC compared to chemotherapy alone. In terms of ≥3 treatment-related adverse events, patients receiving immunotherapy combined with chemotherapy were at higher risk than chemotherapy alone (OR 1.73, 95% CI 1.47-2.05).
conclusionsThis meta-analysis suggested that immunotherapy combined with chemotherapy yielded a better ORR, PFS, and OS, and a higher incidence of treatment-related adverse events as the first-line therapy for patients with PD-L1-negative and driver-gene-negative nonsquamous advanced NSCLC in comparison to chemotherapy alone. A rational treatment protocol should be selected according to the individual condition of the patients.
