Needle Aspiration Versus Closed Thoracostomy in the Treatment of Spontaneous Pneumothorax: A Meta-analysis.
Synthesis in Lung, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
purposeTo compare the effectiveness and safety between needle aspiration (NA) and closed thoracostomy (CT) method in adult spontaneous pneumothorax (SP) patients and to explore the most effective and safe protocol by using meta-analysis method. MATERIALS AND
methodsThis study was based on Cochrane methodology for conducting meta-analysis. Only randomized controlled trials were eligible for this study. The participants were adults who had SP. The Review Manager Database was used to analyze selected studies.
resultsNine RCTs involving 665 patients were included. Although the initial success rate of CT was higher, the two groups were not statistically significant (RR 0.87 [95% CI 0.76-1.00]; p = 0.05). Compared the NA group, the use of CT method to treat SP significantly increased complications (RR 0.17 [95% CI 0.06-0.45]; p = 0.0003) and operation rate (RR 0.57 [95% CI 0.35-0.95]; p = 0.03). There was no significant difference in the 1-week success rate, admitted rate, 3-month recurrence rate, 1-year recurrence rate, and recurrence time between the two groups. Subgroup analysis of primary spontaneous pneumothorax (PSP) and secondary spontaneous pneumothorax (SSP) patients showed that the initial success rate of the CT method was higher than NA group (RR 0.74 [95% CI 0.60-0.92]; p = 0.007).
conclusionsFor the treatment of SP, NA method could significantly decrease complication rate, operation rate, as well as hospital stay length, compared with the CT method. Subgroup analysis indicated that the use of CT method in SSP and PSP patients might increase the initial success rate.
