Prognostic Impact of Ground-Glass Opacity in Clinical Stage IA Non-Small Cell Lung Cancer With Interstitial Lung Abnormalities.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesGround-glass opacity (GGO) component is a favourable prognostic factor in non-small cell lung cancer (NSCLC), whereas NSCLC with interstitial lung abnormalities (ILA) generally has poorer prognoses. We investigated the clinical significance of GGO in patients with NSCLC and ILA.
methodsAmong 1319 patients who underwent pulmonary resection for clinical stage IA NSCLC at 2 institutions between 2010 and 2020, we retrospectively assessed 216 patients with ILA based on preoperative CT. Patients were divided into 2 groups: pure solid tumours without GGO and subsolid tumours with GGO.
resultsAmong 216 patients with ILA, 146 (68%) had pure solid tumours and 70 (32%) had subsolid tumours. Subsolid tumours had significantly better prognoses than pure solid tumours (5-year overall survival, 69.7% vs 48.6%, P = .0008; 5-year recurrence-free survival, 69.7% vs 42.3%, P < .0001). Recurrence occurred in 4 patients (6%) with subsolid tumours and 41 (28%) with pure solid tumours. Although the 5-year cumulative incidence of lung cancer deaths was significantly lower in subsolid tumours than in those with pure solid tumours (2.6% vs 23.6%, P = .0011), an increase in other causes of mortality after 2 years post-surgery in subsolid tumours resulted in a comparable 5-year cumulative incidence of other causes of death (28.4% vs 36.1%, P = .260).
conclusionsIn clinical stage IA NSCLC with ILA, subsolid tumours have a lower lung cancer mortality than pure solid tumours; however, higher other-cause mortality after 2 years contributes to poorer overall survival. Optimizing comorbidity management may improve long-term prognosis.
