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

backgroundThe relationship between operative invasiveness and the prognosis in non-small cell lung cancer (NSCLC) patients who have undergone surgery has been controversial.

methodsClinical data were analyzed for 463 NSCLC patients. Operative invasiveness was defined by wound length, operation time, and the postoperative C-reactive protein (postCRP) level. The operative approach was divided into video-assisted thoracic surgery (VATS) and thoracotomy.

resultsThe wound length and operation time were significantly correlated with the postCRP level (correlation coefficient (CC) = 0.39, p <  0.01; CC = 0.54, p <  0.01, respectively). The postCRP level in the VATS group was significantly lower than that in the thoracotomy group (12.2 mg/dl vs 20.58 mg/dl, p <  0.01). The relapse-free survival differed significantly based on wound length (p <  0.01), operation time (p = 0.01), CRP level (p <  0.01), and operative approach (p <  0.01). The carcinoembryonic antigen level (hazard ratio [HR], 1.58; p = 0.02), pathological stage (pStage) (HR, 2.57; p <  0.01), vascular invasion (HR, 1.95; p = 0.01), and preoperative CRP level (preCRP) (HR, 1.91; p <  0.01) were identified as significant prognostic factors for relapse-free survival in a multivariate analysis. Furthermore, the multivariate analysis showed that smoking history (HR, 2.36; p = 0.03), pStage (HR, 3.26; p <  0.01), and preCRP level were significant prognostic factors for overall survival.

conclusionPreoperative CRP level was associated with poor prognosis. Although the VATS approach might be less invasive procedure for NSCLC patients, operative invasiveness does not affect the prognosis.
