1 · What the graph read from 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.

2 · The registry

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

Group B streptococcus (GBS) is a uropathogen capable of causing urinary tract infections (UTIs), although its role in male patients is not well characterized. This study aimed to investigate the capsule serotypes and clonal relationships of GBS strains isolated from male patients with urinary symptoms. A total of 69 GBS isolates from male patients admitted to Adana City Hospital were analyzed. Capsule serotypes were determined by multiplex PCR (Thermo Fisher Scientific, USA), and clonal relationships were assessed using pulsed-field gel electrophoresis (PFGE) (Bio-Rad, USA). The most common capsule serotypes identified were Ib (n = 28; 40.6%), V (n = 23; 33.3%), and III (n = 18; 26.1%). All isolates were susceptible to ampicillin and vancomycin. Resistance rates were 69.5% for ciprofloxacin, 30.4% for erythromycin, 24.6% for clindamycin, and 11.5% for tetracycline. PFGE analysis revealed that two isolates from different patients, collected on separate dates, were 100% identical, indicating possible clonal spread. In conclusion, although GBS-related UTIs are uncommon in male patients, the data obtained in this study provide valuable insights for future epidemiological research on GBS in this population.
