A strong association between TTF-1 expression and interstitial lung disease in predicting the efficacy of PD-1 inhibitor for nonsquamous NSCLC patients.

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
Background: Thyroid transcriptional factor-1 (TTF-1) is associated with the development of interstitial lung disease (ILD) and is a mutational target in lung adenocarcinoma with ILD. TTF-1 expression is also associated with the efficacy of pemetrexed-based chemotherapy for nonsquamous nonsmall cell lung cancer (NS-NSCLC). However, the relationship between TTF-1 expression and the efficacy of immunotherapy using programmed cell death 1 inhibitor (PD-1i), especially in lung cancer patients with ILD, remains unclear. Methods: Medical data of NS-NSCLC patients treated with PD-1i at multiple centres were analysed retrospectively. Patients were divided into those with or without concomitant ILD, with the two cohorts further stratified by TTF-1 expression. Results: The study population included 62 NS-NSCLC patients, 34 with and 28 without ILD. Median progression-free survival (PFS) during PD-1i treatment was significantly shorter in TTF-1-negative than -positive patients (2.0 Conclusion: TTF-1 expression in NS-NSCLC patients with ILD may predict prognosis when treated with PD-1i.
