C-PLAN index as a prognostic factor for patients with previously untreated advanced non-small cell lung cancer who received combination immunotherapy: A multicenter retrospective study.
Article in Thoracic cancer, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
backgroundCombination immunotherapy (immune checkpoint inhibitors and cytotoxic anticancer agents) is widely used as first-line treatment for advanced non-small cell lung cancer (NSCLC). However, the therapeutic effect of combination immunotherapy has not been fully investigated. C-reactive protein, performance status, lactate dehydrogenase, albumin, and derived neutrophil-to-lymphocyte ratio (C-PLAN) are useful biomarkers for predicting the prognosis of NSCLC; however, there are no reports examining the C-PLAN index, which combines these five factors in a single prognostic factor.
methodsWe retrospectively collected data from 178 patients with previously untreated advanced NSCLC who received combination immunotherapy at multicenter institutions in Nagano Prefecture between December 2018 and April 2022. We investigated the utility of the C-PLAN index as a prognostic factor using Cox regression analysis and correlated it with survival.
resultsThe good and poor C-PLAN index groups included 85 and 93 patients, respectively. The good C-PLAN index group had a longer median progression-free survival (PFS) (10.7 vs. 6.0 months; p = 0.022) and overall survival (OS) (25.3 vs. 16.5 months; p = 0.003) than the poor C-PLAN index group. The C-PLAN index was an independent favorable prognostic factor that correlated with PFS and OS in multivariate analysis. The good C-PLAN index group had a higher proportion of never-smokers (16.5 vs. 4.3%; p = 0.007) and stage III disease/postoperative recurrence (32.9 vs. 15.1%; p = 0.005) than the poor C-PLAN index group.
conclusionThe C-PLAN index is a useful prognostic factor for patients with previously untreated advanced NSCLC undergoing combination immunotherapy.
