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

objectiveThe induction of artificial pneumothorax has many intraoperative advantages. However, few reports on the postoperative effects of artificial pneumothorax induction are available. In this study, we investigated the effect of artificial pneumothorax on postoperative clinical course in patients with mediastinal tumors.

methodsWe retrospectively investigated the clinical courses of 89 patients who had undergone mediastinal tumor resection between January 2010 and December 2020. Sixty-five patients had undergone resection with artificial pneumothorax.

resultsThe tumor location significantly varied across patients. The proportion of patients in whom artificial pneumothorax was induced was higher among those having anterior mediastinal tumors. The number of ports and the total skin incision length were significantly higher in patients without artificial pneumothorax. The C-reactive protein level elevation on postoperative day 2 and pleural effusion at 24 h after surgery were significantly higher in patients without artificial pneumothorax. Furthermore, the albumin level reduction and hospital stay after surgery were significantly lower in patients with artificial pneumothorax. Multiple regression analysis showed that the use of artificial pneumothorax was an independent predictive factor of the C-reactive protein level elevation on postoperative day 2 and pleural effusion at 24 h after surgery. In patients without artificial pneumothorax, the operation time positively correlated with the C-reactive protein level (r = 0.646, P < 0.001).

conclusionsArtificial pneumothorax suppressed the postoperative inflammatory response, pleural effusion, and albumin reduction, and shortened the hospital stay in patients undergoing mediastinal tumor surgery.
