The bacteriology of bronchiectasis patients and relation to disease severity.
Article in BMC pulmonary medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundBronchiectasis is a progressive pulmonary disease with repeated cough, expectoration and frequent respiratory infections. Every patient should have sample collected for routine bacteriological culture. Determining the disease's severity can help with therapy and follow-up choices. AIM OF THE STUDY: To detect the bacteriology of bronchiectasis patients and relation to disease severity.
results60 patients with bronchiectasis exacerbation were investigated at chest department of Fayoum University Hospital. Broncho alveolar lavage for culture and sensitivity was done. Disease severity was assessed by cough score, mMRC dyspnea score, oxygen saturation, no of lobes affected in CT chest and modified rieff score, Spirometry and classification of severity by FEV1, and finally FACED and BSI scores were calculated. Isolation of H.Influenza represents 40%, Pseudomonas represents 26.7%, Klebsiella represents 20%, Staph aureus represents 10% and Pseudomonas& Klebsiella represent 3.3%. There was a statistically significant lower mean of oxygen saturation in cases infected with both pseudomonas and Klebsiella. There was a statistically significant high percentage of mild Modified Reiff score among cases infected with H. influenza, moderate degree among cases infected with Klebsiella, but severe degree among cases infected with pseudomonas.
conclusionH. influenzae consider as a major pathogen isolated by BAL culture in patients with bronchiectasis exacerbation, followed by P. aeruginosa, then klebsiella then S. aureus. Cases infected with P. aeruginosa and klebsiella have the worst oxygen saturation. The highest modified Rieff score was in P. aeruginosa than other isolated organisms.
