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

Secondary spontaneous pneumothorax (SSP) carries a clinically important risk of recurrence, but the available evidence is dispersed across heterogeneous disease-specific and treatment cohorts. This systematic review aimed to identify clinical, radiological, physiological, disease-related, clinical-course, and treatment-related determinants of recurrence after SSP. PubMed/MEDLINE was searched on 19 July 2026 without a date restriction. Adult and adult-inclusive SSP cohorts were eligible, as were mixed spontaneous-pneumothorax cohorts containing patients with SSP when a recurrence determinant was evaluated. Evidence without SSP-specific estimates was classified as indirect. Of 77 records screened, 50 reports were sought, 31 were retrieved and assessed, two were excluded at full text, and 29 studies were included. Nineteen reports could not be retrieved and were classified as unavailable rather than scientifically excluded. Because of substantial heterogeneity in populations, interventions, recurrence definitions, follow-up periods, and effect measures, a narrative synthesis was undertaken without meta-analysis. Recurrence was associated with severe emphysematous or fibrotic lung damage, non-chronic obstructive pulmonary disease (non-COPD) aetiology, prolonged air leak, impaired forced expiratory volume in one second (FEV1), Birt-Hogg-Dubé syndrome, chest deformity in Marfan syndrome, and selected malignancy-related radiographic features. Definitive recurrence prophylaxis, video-assisted thoracoscopic surgery (VATS)-based procedures, pleural interventions, and medical pleurodesis were generally associated with lower recurrence than drainage alone. Technical comparisons suggested that the effectiveness of lesion control and pleural intervention may be more important than the number of thoracoscopic ports. Evidence favouring thoracotomy over VATS arose from mixed cohorts and should be interpreted cautiously. SSP recurrence risk should therefore be assessed using the underlying disease, structural lung damage, physiological reserve, behaviour of the index episode, and suitability for definitive pleural intervention.
