Time to positive culture can differentiate post-neurosurgical coagulase-negative Staphylococci other than S epidermidis meningitis from contamination: A case-control observational study.
Observational study in Journal of clinical laboratory analysis, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectiveTo explore the characteristics of coagulase-negative Staphylococci other than Staphylococci epidermidis (Nse-CoNS) meningitis and to apply cerebrospinal fluid (CSF) times to positivity culture (TTPC) for the precise differentiation of meningitis from contamination.
methodsWe conducted a case-control study to accomplish the following: First, we retrospectively reviewed records of post-neurosurgical patients' CSF that yielded Nse-CoNS from January to October 2019 at the Beijing Tiantan Hospital; 17 clinical and 12 laboratory characteristics were reviewed. Second, we investigated the TTPC of the Nse-CoNS, the cutoffs, and corresponding parameters to differentiate Nse-CoNS meningitis from contamination.
resultsIn this study, a total of 146 patients with Nse-CoNS CSF culture positive were enrolled. The average TTPC in the Nse-CoNS meningitis group was significantly shorter than in the contamination group (20.2 ± 5.0 hours and 30.2 ± 12.6 hours, respectively, P < .05). The area under curve (AUC) of the model was 0.802. A TTPC of 20.0 hours had 94.3% sensitivity and a negative value of 90.2% for predicting Nse-CoNS meningitis.
conclusionsNse-CoNS meningitis often causes confusion in clinical diagnosis. In this study, we evaluated the clinical predictive factors of Nse-CoNS meningitis and confirmed that the median TTPC in the Nse-CoNS meningitis group was significantly shorter than in the contamination group. A TTPC shorter than 20.0 hours was associated with Nse-CoNS meningitis, while a TTPC longer than 20.0 hours was associated with Nse-CoNS contamination. This information will be helpful for the rapid diagnosis of Nse-CoNS meningitis.
