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

purposeThe purpose of this retrospective study was to determine the long-term efficacy of a stapled bullectomy without any symphysial procedures under videoassisted thoracoscopic surgery (VATS).

methodsA total of 121 sides of 112 patients who underwent a stapled bullectomy alone for primary spontaneous pneumothorax were retrospectively reviewed. There were 48 sides of 45 patients who underwent VATS (VATS group) and 73 sides of 67 patients who underwent open surgery (thoracotomy group).

resultsThere were 12 recurrences that occurred during the follow-up periods in the VATS group (24.5%), and 3 in the thoracotomy group (4.1%). The cumulative recurrence rates in the VATS group at 2 and 10 years after a bullectomy were 16.3% and 27.5%, whereas in the thoracotomy group the recurrence rates were 2.9% and 4.9%, respectively (P < 0.001).

conclusionsThe long-term outcome of a VATS stapled bullectomy was unsatisfactory as a radical therapy for primary spontaneous pneumothorax. A symphysial procedure should therefore be added to VATS stapled bullectomy in order to prevent long-term postoperative recurrence.
