Interpleural distance predicts persistent air leak after initial primary spontaneous pneumothorax.
Article in Journal of thoracic disease, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05358158 (Efficacy of Avoiding Chest Drain After Video-assisted Thoracoscopic Surgery Wedge Resection), which is not on this map. Cited by 4 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.

Abstract
backgroundInitial surgical intervention for a first episode of primary spontaneous pneumothorax (PSP) is controversial. However, if air leak persists after initial drainage, surgical treatment is recommended. Therefore, we investigated risk factors for persistent air leak (PAL) in patients with a first episode of PSP.
methodsWe retrospectively analyzed 122 patients with a first episode of PSP between January 2011 and April 2019. PAL was defined as air leak lasting 72 hours or longer. Early admission was defined hospital admission within 24 hours of symptom onset. Three methods were used to estimate pneumothorax size on chest X-rays taken at admission: interpleural distance, apex-cupola distance, and Light index.
resultsAmong 122 patients, 55 developed PAL (PAL group) and 67 did not (non-PAL group). The size of pneumothorax was significantly larger in the PAL group than in the non-PAL group in all three methods of assessment (P<0.001). Early hospital admission was significantly associated with PAL (P=0.026). Logistic regression analysis revealed that the odds ratio for PAL per unit increase in pneumothorax size evaluated with the interpleural distance was 1.304 (P<0.001). Multivariate logistic regression analysis showed that interpleural distance at the hilum and early admission (P<0.001, P=0.008, respectively) were independent predictors of PAL in patients with a first episode of PSP.
conclusionsIn our study, we demonstrated that the interpleural distance at the hilum is a simple and effective predictor of PAL in patients with a first episode of PSP. Our data may help decision-making for initial surgical treatment in these patients.
