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
purposeTo investigate trends in surgical site infections (SSI) in adult spinal deformity (ASD) surgery over 13 years, beginning with three-column osteotomies (3-COs) and continuing through the introduction of lateral lumbar interbody fusion (LLIF) and vancomycin powder, as well as during the COVID-19 pandemic.
methodsConsecutive 633 patients who underwent corrective and fusion surgeries were enrolled at a single institution between 2010 and 2022. The incidence of SSI and details of patients with SSI were obtained from the surgical records.
resultsThe overall incidence of SSIs was 6.0% (n = 38). Univariate analysis showed that SSI was significantly associated with older age (p = 0.036), male (p = 0.002), diabetes mellitus (p = 0.002), albumin levels (p = 0.019), revision cases (p = 0.003), surgery performed during the COVID-19 pandemic (p = 0.047), and iliac fusion (p = 0.046). In the multivariate analysis, revision cases (odds ratio, 3.73), male patients (odds ratio, 2.68), diabetes mellitus (odds ratio, 2.56), and albumin level (odds ratio, 0.44) were independent risk factors. The incidence of SSI was highest in the first three years, when 3-COs were the mainstay of the surgical procedure, reaching 10.6%. After the introduction of LLIF and intraoperative vancomycin (VCM) powder, the incidence decreased to 4.8%. During the COVID-19 pandemic, the incidence was lowest at 1.3% compared to other terms.
conclusionsLower SSI rates were observed after the introduction of staged LLIF-based surgery and intrawound vancomycin powder and during the COVID-19 period; however, these temporal associations should be interpreted cautiously because multiple changes in practice occurred concurrently.
