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

backgroundFirst-line chemoimmunotherapy (CIT) has improved overall survival (OS) and progression-free survival (PFS) outcomes among patients with non-small cell lung cancer (NSCLC). The immunological and nutritional statuses of patients fluctuate during treatment using immune checkpoint inhibitors, and are closely related to treatment outcomes. However, it is unclear whether these markers are significant in patients who are receiving CIT.

methodsThis retrospective single-center study evaluated 34 consecutive Japanese patients with NSCLC who were treated using first-line CIT. Previously reported markers that reflect immunological and nutritional statuses were evaluated at three time points: at the start of CIT, after three weeks, and at the end of induction therapy.

resultsThe median PFS was 7.2 months (95% confidence interval: 6.3 months-not reached) and the median OS was not reached (95% confidence interval: 9.6 months-not reached). The PFS duration was significantly associated with the baseline neutrophil-to-lymphocyte ratio and the three-week values for the modified Glasgow prognostic score, C-reactive protein-albumin ratio, prognostic nutrition index, and advanced lung cancer inflammation index. The OS duration was significantly associated with the pre-treatment values for the neutrophil-to-lymphocyte ratio and advanced lung cancer inflammation index, as well as the prognostic nutrition index at the end of induction therapy.

conclusionsImmunological and nutritional markers could be useful for predicting the outcomes of CIT for Japanese patients with advanced non-small cell lung cancer. The timing of their evaluation may also be important. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: Overall survival in patients receiving first-line chemoimmunotherapy for advanced lung cancer were associated with pretreatment values of neutrophil-to-lymphocyte ratio, advanced lung cancer inflammation index, and the prognostic nutrition index at the end of induction therapy. WHAT THIS STUDY ADDS: Repetitive evaluation of immunological and nutritional markers may be useful for guiding prognostication and treatment selection for Japanese patients with advanced lung cancer.
