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 causes and treatment of pneumothorax in older patients are different from those in younger patients. However, studies on this topic are limited thus; pneumothorax in older patients is often inadequately managed. The purpose of this research was to investigate the characteristics of pneumothorax in patients over 45 years old, understand patterns of management and factors of recurrence, and propose reasonable guidelines for the treatment of older patients.

methodsOf 438 consecutive patients with spontaneous pneumothorax between 2013 and 2017, 120 patients were enrolled and divided into two groups: (I) 45-64 years and (II) ≥65 years. Basic demographics, treatment modality, and patterns of surgery/recurrence were described. Clinical variables were compared between groups, and risk factors of recurrence were analyzed using logistic regression.

resultsThe study population was divided into group A (younger, n=61) and B (older, n=59). Chest tube drainage was the most common procedure for both groups and chemical pleurodesis was applied more often in B (27%

conclusionsRadiological findings of emphysema or bullae/blebs are risk factors for recurrence of pneumothorax in elderly patients. Surgery in selected patients is an effective method for decreasing the recurrence rate.
