Bacterial culture and antibiotic resistance pattern in chronic rhinosinusitis among patients who underwent sinus surgery.
Article in BMC infectious diseases, 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
objectiveChronic rhinosinusitis (CRS) is a common inflammatory condition affecting a large portion of the population worldwide. Bacterial infections are one of the causes of recurrence and treatment resistance in CRS. Our goal is to describe antimicrobial resistance patterns in patients with CRS who underwent functional endoscopic sinus surgery (FESS).
methodsA retrospective chart review was conducted at King Abdulaziz University Hospital, which included 444 patients who underwent 444 FESS procedures between January 2014 and December 2018.
resultsA total of 98% of the patients underwent primary FESS. Of the 803 cultured samples, 611 (76%) yielded bacterial growth. The most frequently isolated organisms were Staphylococcus aureus (32%), Klebsiella pneumoniae (10.6%), and Pseudomonas aeruginosa (9.7%). Gram-positive organisms were most susceptible to vancomycin and ofloxacin.
conclusionA wide range of microorganisms were obtained from patients with CRS. The antibiotic resistance of microorganisms in CRS is an important issue because many of the pathogens are noted to be resistant to commonly used antibiotics. CLINICAL TRAIL: Not applicable.
