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

backgroundTo investigate the impact of programmed death-ligand 1 (PD-L1) polymorphisms on the prognosis of non-small cell lung cancer (NSCLC) patients treated with curative radiotherapy.

methodsFour single nucleotide polymorphisms (SNPs) (rs822336G>C, rs822337T>A, rs822338C>T, and rs2297136A>G) in the PD-L1 gene were evaluated in 124 NSCLC patients. Clinical stage was I in 28, II in 17, and III in 79 patients. Fifty-seven patients received radiotherapy alone, including 28 patients who received stereotactic body radiotherapy. Sixty-seven patients received sequential or concurrent chemoradiotherapy. Risk factors for survival outcomes were analyzed with the log-rank test and multivariate Cox proportional hazards models.

resultsThe rs822336GC+CC genotype was associated with better overall survival (OS) (hazard ratio [HR] = 0.60, 95% confidence interval [CI] = 0.37-0.97, p = 0.036) and regional failure-free survival (RFFS) (HR = 0.32, 95% CI = 0.14-0.76, p = 0.009), compared with rs822336GG genotype. The rs822337TA+AA genotype was associated with better OS (HR =0.54, 95% CI = 0.34-0.88, p = 0.014), progression-free survival (PFS) (HR = 0.64, 95% CI = 0.41-0.99, p = 0.046), and RFFS (HR = 0.38, 95% CI = 0.17-0.81, p = 0.013), compared with rs822337TT genotype. Three SNPs (rs822336, rs822337, and rs822338) were in linkage disequilibrium. Combined GTC and GTT (GT*) haplotype was associated with significantly worse OS (p = 0.018), PFS (p = 0.044), and RFFS (p = 0.038), compared with those with other combined haplotypes. Patients with diplotypes of two GT* haplotypes showed significantly worse OS (p = 0.023) and RFFS (p = 0.014) than those with other diplotypes.

conclusionsThese findings suggest that PD-L1 polymorphisms could be predictive markers for NSCLC patients receiving radiotherapy.
