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
Introduction: Delayed diagnosis and therapy initiation for pyogenic spondylitis can have severe and fatal consequences. Early diagnosis and intervention are crucial in the treatment of pyogenic spondylitis. This multicenter cross-sectional study with prospective case series aimed to identify factors influencing the time from symptom onset to the diagnosis of pyogenic spondylitis. Methods: Patients hospitalized with pyogenic spondylitis between 2019 and 2023 were included. Patients were classified into 2 groups: the delayed diagnosis group (>30 days from the onset of initial symptoms to the diagnosis of pyogenic spondylitis) and the early diagnosis group (within 29 days). Risk factors for delayed diagnosis were analyzed. Results: A total of 74 patients (42 men and 32 women; mean age: 70.2 years) from 5 institutions were included. Univariate analysis of risk factors for delayed diagnosis revealed that the significant risk factors included advanced age (p=0.03), low white blood cell count (p<0.01), low C-reactive protein level (p<0.05), and semi-rigid spinal level, based on the spinal instability neoplastic score classification (p=0.05). Multivariate analysis for delayed diagnosis showed that the location at the semi-rigid spinal level was a significant risk factor (p=0.02). The vertebral bone destruction rate and abscess cavity index in the delayed diagnosis group were significantly higher than those in the early diagnosis group (p<0.01 and p<0.01, respectively). Conclusions: Significant risk factors for delayed diagnosis of pyogenic spondylodiscitis include infection at the semi-rigid thoracic spinal level. Early diagnosis of spondylodiscitis is crucial because delayed diagnosis can lead to progressive bone destruction and the formation of large abscesses. Increased awareness of thoracic spinal infections, which can easily delay diagnosis, could help in the early diagnosis and treatment of pyogenic spondylodiscitis.
