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

The present study aimed to unveil the biological role of carbonic anhydrase IV (CA IV) and its association with clinical pathological characteristics and prognostic significance in non-small cell lung cancer (NSCLC). The relative expression level of CA IV was measured by reverse transcription-quantitative polymerase chain reaction in 114 resected NSCLC tumors and matched adjacent normal tissues and NSCLC cell lines. Overexpression and cell proliferation were assessed in human NSCLC cell lines transfected with CA IV mRNA by lentivirus-mediated technology. The association of CA IV expression with clinical pathological features and overall survival in 114 cases of NSCLC patients was analyzed. It was demonstrated that CA IV expression was significantly downregulated in NSCLC tumors and six cell lines. Reduced expression of CA IV was significantly correlated with lymph node metastasis. The overall survival of NSCLC patients with low CA IV expression was significantly shorter compared with the high expression group. Overexpression of CA IV suppressed cell proliferation in A549 and NCI-H1299 cells. The results indicate that low expression of CA IV promotes cell proliferation and serves as an indicator for poor prognosis in NSCLC.
