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

purposeTo investigate the risk factors of recurrence of pneumothorax following thoracoscopic bullectomy in young adults.

methodsBetween January, 2005 and September, 2015, 167 patients aged ≤40 years underwent initial thoracoscopic bullectomy for primary spontaneous pneumothorax (PSP) at our hospital. Recurrence-free probability was calculated from the date of surgery to recurrence or last follow-up, using the Kaplan-Meier method.

resultsSixteen (9.6%) of the 167 patients suffered a recurrence (collective total, 16 recurrences). The recurrence-free intervals were 3-107 months (median 25.8 months), and the 5-year recurrence-free probability was 85.9%. Multivariate Cox analysis demonstrated that age ≤23 years (p = 0.029) and a history of ipsilateral pneumothorax before surgery (p = 0.029) were significantly associated with higher risk of recurrence. The 5-year recurrence-free probability was 72.3% for patients aged ≤23 years and a history of ipsilateral pneumothorax before surgery and 94.1% for those with neither of these factors (p = 0.001). Recurrence developed within 3 years after surgery in 14 of the 16 patients.

conclusionsPatients ≤23 years of age with a history of ipsilateral pneumothorax before surgery are at significantly high risk of its recurrence, frequently within 3 years; thus, the risk of postoperative recurrence of a pneumothorax must be kept in mind.
