Secondary spontaneous pneumothorax in cancer patients.
Article in Journal of thoracic disease, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
backgroundMalignancy-associated secondary spontaneous pneumothorax (MSSP) poses significant challenges due to limited survival. By assessing risk factors associated with a MSSP recurrence, there is potential to identify patients who could benefit from early intervention intended to prevent recurrence.
methodsWe performed a retrospective cohort study of patients with MSSP. The primary outcome was time to MSSP recurrence. We used a competing risk model to identify risk factors associated with MSSP recurrence.
resultsA total of 2,532 patients were diagnosed with pneumothorax, with 114 having MSSP but only 96 were evaluable for the time-to-recurrence analysis. Of the 96 patients, 9 (9.4%) patients experienced recurrent MSSP, and 58 (60.4%) patients died during the study's follow-up period. The estimated cumulative incidence (CI) of MSSP considering death as a competing risk was 10.1% at 15 months. The univariable model identified the following covariates as associated with MSSP recurrence: mediastinal shift (HR 12.30, 95% CI: 3.44-43.91, P<0.001), distance from lung apex to thoracic cupola (HR 1.02, 95% CI: 1.00-1.03, P=0.003), and distance between visceral and chest wall at the hilum (HR 1.02, 95% CI: 1.00-1.03, P=0.026).
conclusionsAlthough the incidence of MSSP recurrence was found to be low, clinical factors such as sarcoma, the associated mediastinal shift, greater distance from lung apex to thoracic cupola, greater distance between visceral and chest wall at the hilum were found to be risk factors for MSSP recurrence.
