A novel percutaneous aspiration sclerotherapy for staged volume reduction of giant single bulla in the treatment of COPD combined with pulmonary bullae.

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
backgroundThe efficacy of a novel technique-percutaneous aspiration sclerotherapy for staged volume reduction of giant single bulla-in patients with chronic obstructive pulmonary disease (COPD) combined with pulmonary bullae remains unclear.
methodsA retrospective study was conducted on 40 COPD patients with pulmonary bullae who underwent the novel percutaneous aspiration sclerotherapy for staged volume reduction of giant single bulla technique. Pulmonary bullae size, pulmonary function, blood gas analysis, six-minute walk test (6MWT), modified Medical Research Council (mMRC) score and St. George 's Respiratory Questionnaire (SGRQ) were assessed before and after the procedure. Related complications were also recorded.
resultsThe average size of the giant bullae in the 40 patients was 12.67 ± 2.49 cm. Compared with preoperative data, PaO
conclusionPercutaneous aspiration sclerotherapy for staged volume reduction of giant single bulla is a feasible treatment for pulmonary bullae, involving a straightforward procedure. Nevertheless, its long-term clinical efficacy remains to be further validated in follow-up studies.
