Quality of life in patients with non-small cell lung cancer treated with PD-1/PD-L1 inhibitors: a 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
backgroundImmune checkpoint inhibitors (ICIs) have dramatically prolonged survival in non-small cell lung cancer (NSCLC) patients, but little research had focused on its impact on quality of life (QoL). The purpose of our study was to compare the QoL in patients with NSCLC treated with programmed cell death protein-1/programmed cell death-ligand 1 (PD-1/PD-L1) inhibitors versus chemotherapy.
methodsWe searched for randomized controlled trials utilizing the Quality of Life Questionnaire Core 30 items (QLQ-C30) and the EuroQol Five Dimensions Questionnaire-3L (EQ-5D-3L) to assess the QoL of NSCLC treated with PD-1/PD-L1 inhibitors versus chemotherapy. We collected hazard ratios (HRs) for the time from baseline to the first clinically significant deterioration (TTD) and effect size as the difference in mean change between and within treatment groups in patients' reported outcomes (PROs). (PROSPERO registration number: CRD42022296680).
resultsIn the five trials reported by QLQ-C30, TTD was longer in PD-1/PD-L1 inhibitors compared with control groups (HR = 0.86; 95% CI = 0.76, 0.97; P = 0.013), with similar results in terms of physical function, role function, and pain. The difference in mean change between the PD-1/PD-L1 inhibitors group and the chemotherapy group in QLQ-C30 and EQ-5D VAS was 3.64 (95% CI = 1.62, 5.66; P = 0.001) and 4.74 (95% CI = 2.65, 6.83; P = 0.001), which supported PD-1/PD-L1 inhibitors. However, for the EQ-5D utility index, there was no statistically significant difference between the two groups, with a mean change difference of 0.03 (95% CI = -0.01, 0.07; P = 0.094). The mean change from baseline to follow-up in PD-1/PD-L1 inhibitors group was 2.57 (95% CI = 0.43, 4.71; P = 0.019), and chemotherapy group was -1.31 (95% CI = -3.71, 1.09; P = 0.284), correspondingly. The subgroup analysis showed that no difference was observed between open-label and double-blind trials in patients treated with chemotherapy or PD-1/PD-L1 inhibitors.
conclusionIn conclusion, PD-1/PD-L1 inhibitors could improve the QoL of patients with NSCLC compared to chemotherapy and reduce unfavorable symptoms during treatment.
