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

backgroundPostoperative recurrent pneumothorax (PORP) can arise after surgery for primary spontaneous pneumothorax (PSP) that is recurrent or involves prolonged air leakage. In this study, which included 265 patients (279 cases) with PSP who underwent surgery at our department, the percentage of patients that did not experience PORP was compared between a group that underwent bullectomy alone (group A) and a group in which the staple line and the surrounding visceral pleura were covered with a PGA sheet after bullectomy (group B) in order to study the utility of PGA sheets for preventing PORP.

methodsAmong the patients with PSP who underwent surgery, the cases of 92 patients (98 cases) from Group A and 173 patients (181 cases) from Group B were reviewed retrospectively. The incidence rates of PORP in these two groups were statistically analyzed in addition to the associations between PORP and age, gender, the affected side, height, body weight, height/weight ratio, smoking habits, or the surgical procedure.

resultsIn total, 96.7% of the patients in group B did not suffer PORP, which was significantly higher than the equivalent figure for group A (83.7%, log-rank test: P=0.0003). Moreover, among the examined parameters, only covering the staple line with a PGA sheet was found to be an independent prognostic factor (Cox regression: P=0.0003; HR =0.212; 95% CI, 0.082-0.547).

conclusionsIt was revealed that when bullectomy is performed in patients with PSP, wide coverage of the staple line and the surrounding visceral pleura with a PGA sheet significantly reduces the risk of PORP.
