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

backgroundTo investigate the development of neogenetic bullae or blebs on 1-year postoperative chest computed tomography after video-assisted thoracic surgery (VATS) in young patients with primary spontaneous pneumothorax (PSP).

methodsIn this prospective study, 10- to 20-year-old patients with PSP were treated via VATS with additional procedures (bullectomy, cold coagulation, coverage, pleural abrasion, or chemical pleurodesis). All patients underwent the additional procedures and computed tomography of the chest 1 year postoperatively for the assessment of neogenetic bullae. Postoperative PSP recurrence was monitored, and recurrence-free survival was evaluated using Kaplan-Meier analysis.

resultsFifty-seven patients (66 cases) aged 17 ± 2 years underwent VATS for PSP and were followed up for 938 ± 496 days. Of the 36 cases at 1-year follow-up, 23 (63.9%) showed neogenetic bullae, which were adjacent to the staple lines in 16 cases (69.6%). The 1- and 2-year recurrence-free survival rates were 88.9 and 85.1%, respectively. Nine of the 66 cases (13.6%) showed recurrence after 869 ± 542 days. A history of contralateral PSP was significantly associated with recurrence.

conclusionsVATS, combined with additional procedures, provides acceptable long-term results in young patients with PSP. Additional procedures reduce the recurrence rate of PSP but do not prevent the occurrence of neogenetic bullae. A history of contralateral PSP is a potential risk factor for post-VATS recurrence in young patients.
