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

Sustained elevation in neutrophil-to-lymphocyte ratio (NLR) after initial chemoradiotherapy (CRT) has been shown to correlate with worse prognosis in a number of solid organ malignancies. Here, we conducted a retrospective observational cohort study involving six sites across Sydney, Australia, including all patients with unresectable stage III NSCLC treated with CRT and consolidation durvalumab between January 2018 and September 2021. Patients had NLR collected prior to CRT and prior to cycle one of durvalumab. We used an NLR value of 3 to stratify patients into high and low groups. Patients with sustained NLR were defined as those with values ≥3 at both timepoints. A total of 145 patients were included in the study. The median age of patients was 66 years with median follow-up of 15.1 months. The median PFS was 17.6 months in the pre-CRT NLR high cohort and not reached (NR) in the pre-CRT NLR low cohort (HR 1.99; p = 0.01). The median OS was 35.5 months in the high pre-CRT NLR cohort compared with 42.0 months in the low pre-CRT NLR cohort (HR 2.62; 95% CI: 1.23-5.56, p < 0.01). Median PFS for sustained NLR elevation was 17.1 months versus NR (HR 1.5; p < 0.01). Pre-CRT NLR and sustained NLR remained independently prognostic for PFS on multivariate analysis (p = 0.04, p = 0.01) respectively. Pre-CRT NLR and sustained NLR is associated with worse PFS outcomes in unresectable stage III NSCLC treated with CRT and durvalumab. Pre-CRT NLR is also associated with worse OS.
