Decreasing Rate of Unknown Bronchiectasis Etiology: Evaluation of 319 Adult Patients with Bronchiectasis.
Article in Turkish thoracic journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveBronchiectasis can have several causes, but there are only a limited number of studies about the prevalence of these causes. Most of the studies in adults are from previous years. This study aimed to identify etiologies in adult patients with bronchiectasis. MATERIAL AND
methodsBetween January 1996 and June 2015, data from 319 patients admitted to a specialized bronchiectasis clinic were analyzed. Diagnoses were confirmed using high-resolution or multislice computed tomography and were retrospectively evaluated.
resultsOf the 319 patients, 187 (58.6%) were women and 132 (41.4%) were men. The mean age was 49.0±17.4 (range 15-83) years. The mean duration of illness was 19.5±14.9 years. There were several common etiologies: (1) post-infections (215; 67.5%, 70 of the 215 patients had tuberculosis); (2) obstructive lung diseases (28, 8.8%); (3) defects in mucociliary clearance (13, 4.2%); (4) connective tissue diseases (8, 2.4%); (5) immunodeficiency (5, 1.5%); (6) structural lung conditions (1, 0.3%); and (7) obstruction of a single bronchus (1, 0.3%). No causes could be established in 41 (12.9%) patients.
conclusionDespite developments in antibiotic therapy and vaccination programs, the most common etiology for bronchiectasis is post-infectious conditions as observed in previous years. However, with improvements in diagnostic tests and procedures, the rate of unknown etiologies has dropped from ≥50% to 12.9%.
