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

Purpose: To identify the impact of CT-defined emphysema on efficacy and immune checkpoint inhibitor-related pneumonitis (ICIP) risk among non-small cell lung cancer (NSCLC) patients who receive ICIs. Methods: PubMed, EMBASE, Web of Science and CNKI databases were searched up to January 8, 2025. Primary outcome was the therapeutic efficacy including the progression-free survival (PFS), overall survival (OS), complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), objective response rate (ORR) and disease control rate (DCR). Second outcome was the ICIP. The hazard ratio (HR) or odds ratio (OR) with 95% confidence interval (CI) were combined. Results: Nine studies with 1076 cases were included. Pooled results demonstrated that the presence of emphysema was significantly associated with improved PFS (HR = 0.43, 95% CI: 0.28-0.67, P < 0.001), OS (HR = 0.43, 95% CI: 0.25-0.75, P = 0.003), PR (OR = 2.10, 95% CI: 1.18-3.75, P = 0.012), PD (OR = 0.60, 95% CI: 0.43-0.83, P = 0.002) and DCR (OR = 1.48, 95% CI: 1.14-1.94, P = 0.004). However, emphysema was associated with increased incidence of ICIP (OR = 1.32, 95% CI: 1.15-1.53, P < 0.001). Conclusion: Based on available evidence, CT-defined emphysema indicates better therapeutic efficacy with longer PFS and OS, but increased risk of ICIP among NSCLC patients receiving ICIs. These findings suggest emphysema may guide personalized immunotherapy decisions in NSCLC.
