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

purposeWhile surgery is an effective treatment for secondary spontaneous pneumothorax (SSP), it can be difficult, because affected patients are usually in a poor general condition. The present study investigated the risk factors of postoperative complications after surgery for SSP.

methodsEighty-eight patients with SSP who underwent surgery from January 2006 to March 2018 were investigated. Clinical data were reviewed, and a multivariate analysis was performed.

resultsEighty-four patients (95%) were males, and the median patient age was 72 years. Underlying lung diseases were chronic obstructive pulmonary disease in 58 patients (65.9%), interstitial pneumonia in 26 (29.5%), and others in 4 (4.5%). Postoperative complications developed in 21 patients (24%). Hospital mortality/prolonged length of stay occurred in 6 patients (7%). A multivariate analysis showed that the preoperative performance status (performance status 0-2 vs. 3, hazard ratio: 6.570, 95% confidence interval: 1.980-21.800) was an independent predictor of postoperative complications.

conclusionSurgery for SSP contributed to early chest tube removal and favorable outcomes. However, rare fatal events occurred, and the patient performance status was a risk factor for postoperative complications. A careful evaluation of each patient's performance status is needed to determine the need for surgical intervention for SSP.
