Clinical impact of tumour burden on the efficacy of PD-1/PD-L1 inhibitors plus chemotherapy in non-small-cell lung cancer.

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
backgroundProgrammed cell death 1 (PD-1)/programmed cell death ligand (PD-L1) inhibitors plus chemotherapy (ICI + Chemo) is the standard treatment for advanced non-small-cell lung cancer (NSCLC). However, the impact of tumour burden on the efficacy of ICI + Chemo remains unknown.
methodsWe retrospectively evaluated 92 patients with advanced NSCLC treated with ICI + Chemo. Tumour burden was assessed as the sum of the longest diameter of the target lesion (BSLD) and number of metastatic lesions (BNMLs). We categorised the patients into three groups based on the combined BSLD and BNML values.
resultsSixty-eight patients (74%) had progressive disease or died. Forty-four patients (48%) in the low-BSLD group had a median progression-free survival (PFS) of 9.5 months, whereas patients in the high-BSLD group had a median PFS of 4.6 months (hazard ratio [HR] = 0.54, p = 0012). Twenty-five patients (27%) in the low-BNML group had a median PFS of 9.6 months, whereas patients in the high-BNML group had a median PFS of 6.5 months (HR = 0.51, p = 0.029). Low-BSLD and low-BNML were associated independently with improved PFS in multivariate analysis. Analysis of the tumour burden combined with BSLD and BNML revealed a trend towards improved PFS as the tumour burden decreased, with median PFS of 22.3, 8.7, and 3.9 months in the low- (N = 13), medium- (N = 42) and high-burden (N = 37) groups respectively.
conclusionsOur findings demonstrated that a high tumour burden negatively impacts the efficacy of ICI + Chemo in patients with advanced NSCLC.
