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

objectivesAccumulating evidence suggests that spontaneous pneumothorax (SP) in women, while relatively rare, has higher rates of post-treatment recurrence than in men. Our aim was to further elucidate the clinical and pathological characteristics of SP in women.

methodsWe retrospectively reviewed 59 female patients with no known underlying lung disease undergoing surgery for their SP from January 1990 to December 2015. We divided the study population into those older than or equal to 50 years and those younger than 50 years, the latter of which was further subdivided into catamenial and non-catamenial pneumothorax.

resultsAmong the study population, 11 (18.6%) had catamenial pneumothorax, 40 (67.8%) had non-catamenial pneumothorax, and 8 (13.6%) were older than 50 years. Pathological diagnoses of catamenial pneumothorax were diaphragmatic endometriosis (n = 4), emphysematous bullae (n = 4), solitary pulmonary capillary hemangiomatosis (SPCH, n = 2), and hematoma (n = 1). By contrast, emphysematous blebs/bullae accounted for all but one case of non-catamenial pneumothorax and all cases in the ≥ 50 years age group. Catamenial pneumothorax showed a significantly higher postoperative recurrence rate compared to non-catamenial pneumothorax (p = 0.0043). The 2-year cumulative ipsilateral recurrence rates of catamenial, non-catamenial, and ≥ 50 years age group were 39.4, 13.8, and 14.3%, respectively.

conclusionsCatamenial pneumothorax affected approximately 20% of female patients undergoing surgery for spontaneous pneumothorax with no underlying lung disease and showed a significantly higher postoperative recurrence rate. Diaphragmatic endometriosis and subpleural blebs/bullae were common pathological findings in catamenial pneumothorax, but SPCH might be a possible pathological diagnosis of catamenial pneumothorax.
