Analysis of tumor cell proliferation (Ki-67) and cell cycle regulator proteins in lung adenocarcinoma with different radiological subtypes.
Article in Respiratory research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThe prognosis of ground glass opacity featured lung adenocarcinomas (GGO-LUAD) is significantly better than that of solid nodule featured lung adenocarcinomas (SN-LUAD), but the underlying reasons remain unclear. Ki-67 and cell cycle regulator proteins are highly expressed in many cancers and linked to prognosis. This study aims to investigate their differential expression in LUAD with different radiological subtypes.
methodsPatients with resected pathological stage 0-III LUAD in our department between July 2019 and March 2022 were retrospectively reviewed. All included patients were divided into four groups based on different consolidation-to-tumour ratio (CTR), we focuses on evaluating the differential expression of Ki-67 and cell cycle regulatory proteins (CCNA2, CCNB1, CCND1, P16, P21, TOP2A, TP53, and pRb) in LUAD with different CTR.
resultsA total of 481 patients were included, 108 in the pure ground glass opacity (PGGO, CTR = 0) group, 103 in the GGO-dominant (GGO-D, 0 < CTR ≤ 0.5) group, 74 in the SN-dominant (SN-D, 0.5 < CTR < 1) group, and 196 in the pure solid nodule (SN, CTR = 1) group. The expression of Ki-67 was significantly higher in elderly patients (P < 0.05), former or current smokers (P < 0.0001), males (P < 0.05), poorly differentiated tumors (P < 0.0001), and tumors with spread through air spaces (STAS) (P < 0.0001), and advanced stage tumors (P < 0.0001). Regardless of age, gender, smoking status and epidermal growth factor receptor (EGFR) mutation status, GGO-LUAD demonstrated significantly lower expression of Ki-67 compared to SN-LUAD. The expression of Ki-67 and cell cycle regulatory proteins (except P21) were significantly lower in the PGGO, GGO-D, SN-D than in the SN group. However, there was no significant difference in the expression of Ki-67 and cell cycle regulatory proteins among the PGGO, GGO-D, and SN-D groups.
conclusionsGGO-LUAD demonstrated significantly lower expression of Ki-67 and cell cycle regulatory proteins compared to SN-LUAD, which may explain the reasons behind the excellent prognosis of GGO-LUAD.
