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

Integrins are transmembranous adhesion molecules postulated to be involved in the brain metastatic cascade. We investigated the correlation of alpha v beta 3 (αvβ3), alpha v beta 5 (αvβ5) and alpha v beta 6 (αvβ6) integrin isoform expression with clinical characteristics including survival times in lung cancer patients with brain metastases (BM). All BM from lung cancer operated at our institution between 1990 and 2011, were identified; where available, primary tumors were retrieved as well. Immunohistochemical analysis for αvβ3, αvβ5 and αvβ6 integrin subunits was performed and correlated with Ki67 and hypoxia-inducible factor (HIF)-1α indexes. Clinical data including survival data were obtained by chart review. 191 BM specimens of 191 patients with histologically confirmed lung cancer (172 non-small cell lung cancer and 19 small cell lung cancer) were included. In 18 patients matched primary tumor samples were available. αvβ6 expression was commonly found on BM tumor cells (103/191; 53.9 %) and showed a significant association with low Ki67 proliferation indices (46 vs. 36 %, p = 0.001, Mann-Whitney U test) and favorable survival times (p = 0.020; log rank test) in patients with non-squamous NSCLC BM. αvβ5 expression was highly expressed on vascular structures (167/191; 87.4 %) and tumor stroma in BM (151/191; 79.1 %) and associated with high HIF-1α indices (60 vs. 90, p = 0.007, Mann-Whitney U test). αvβ3 expression was more frequently found on vascular structures in BM than in primary tumors (68.1 vs. 5.6 %; p = 0.645; Chi square test) and its expression in BM tumor cells correlated with low Ki67 indices (41 vs. 28 %; p = 0.046, Mann-Whitney U test). Expression of αv integrin subunits seem to be of pathobiological and clinical relevance in patients with NSCLC BM. Further investigations of their involvement in the brain metastatic cascade and their role as biomarkers are warranted.
