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
objectivesTo compare the effectiveness and safety of two antibiotic prophylaxis regimens, ciprofloxacin plus gentamicin and ceftriaxone plus cefixime, in preventing infectious complications after transrectal ultrasound-guided prostate biopsy.
methodsThe study retrospectively reviewed 705 consecutive patients who underwent transrectal ultrasound-guided prostate biopsy between January 2020 and January 2024. Group 1 (n = 374) received ciprofloxacin plus gentamicin, and Group 2 (n = 331) received ceftriaxone plus cefixime. All patients underwent standard rectal preparation with povidone-iodine, and needle-tip disinfection with formalin. The primary outcome was the development of post-biopsy infectious complications, while secondary outcomes included sepsis and infection-related hospitalization.
resultsThe two groups were comparable in terms of age, body mass index, prostate-specific antigen levels, and comorbidities. The overall rate of post-biopsy infection was 1.4%, occurring in 1.1% patients in Group 1 and 1.8% patients in Group 2 (p = 0.61). The incidence of complicated urinary tract infection was 0.3% versus 0.9%, and infection-related hospitalization occurred in 0.5% versus 0.3% of patients in Group 1 and Group 2, respectively, with no cases of sepsis observed. In univariable analyses, diabetes mellitus, histopathological chronic prostatitis, and pre-biopsy antibiotic use were not significantly associated with post-biopsy infection.
conclusionThe combination of ceftriaxone and cefixime showed a safety profile broadly consistent with the combination of ciprofloxacin and gentamicin for biopsy prophylaxis. Considering increasing fluoroquinolone resistance and growing restrictions, this cephalosporin-based regimen may be considered a feasible option for transrectal ultrasound-guided prostate biopsy when implemented together with strict antiseptic measures.
