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 registryThe 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.

6 · The paper itselfAbstract
Introduction: Methods: GBS-positive clinical isolates collected at Guangdong Provincial People's Hospital (Guangzhou, China) from 2016 to 2022 were subjected to genomic epidemiology analyses. A total of 72 non-duplicate isolates were included. Multilocus sequence typing (MLST) and whole-genome sequencing (WGS) were used to determine capsular serotypes, sequence types (STs) and clonal complexes (CCs), and to identify antimicrobial resistance genes and virulence determinants, including pilus islands. Results: Among 72 isolates, serotype III predominated (36.1%), followed by serotype V (25.0%). Isolates were assigned to 22 STs within 7 CCs, with ST19 being most common (15.3%). Resistance gene profiling showed Discussion: GBS circulating in Guangzhou shows a serotype distribution dominated by III and V and a diverse clonal structure with ST19 prominence. The high carriage of
