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
purposeThe objective of the study is to analyze the presence of Cutibacterium Acnes in the skin, subcutaneous tissue and deep tissue when performing primary lumbar spine surgery for degenerative pathology.
methodsprospective study including consecutive patients, over 18 years of age, who underwent surgery for degenerative lumbar spine pathology through a posterior approach for the first time. 8 samples were obtained, 6 at the beginning of the intervention (2 skin, 2 subcutaneous, 2 deep tissue) and 2 at the end (1 deep tissue, 1 subcutaneous) for each patient following the Oxford protocol. Age, sex, and presence of previous facet/epidural infiltrations were recorded.
results560 tissue samples were obtained from the 70 patients included. 52.8% were men, with an average of 56.2 years (SD 16.71). 57 samples were positive corresponding to 19 patients (27%). Men (p < 0.008) and patients under 50 years of age (p < 0.018) had more positive cultures. 71% of patients with positive deep tissue at the end of the intervention initially had positive samples in skin or subcutaneous tissue. According to the multivariate logistic regression analysis carried out adjusted for age and sex, having a positive skin and/or subcutaneous tissue sample obtained at the beginning of the intervention implies a 20 times greater risk of having a positive deep tissue culture at the end of the procedure (p 0,00).
conclusionThe results of this study show a colonization rate of Cutibacterium Acnes of 27%,with a higher incidence found in young males.
