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
Objective: Contaminated environmental surfaces contribute to the transmission of pathogens that cause healthcare-associated infections. The present study aimed to assess the efficacy and cost implications of a chlorine-based combined detergent-disinfectant used for environmental decontamination around methicillin-resistant Materials and Methods: The study was conducted over a six-month period in the inpatient wards (medical, surgical, and orthopedic) of Pamela Youde Nethersole Eastern Hospital, Hong Kong Special Administrative Region, People's Republic of China. The surrounding areas of newly diagnosed MRSA patients were divided into two equal halves and decontaminated using either the conventional two-step process (cleaning with detergent followed by disinfection with a 1000 ppm hypochlorite solution) or a new one-step method using a combined detergent-disinfectant. High-touch surfaces in the patients' immediate environment were sampled before and after decontamination to detect MRSA by culture and to measure adenosine triphosphate (ATP) levels. The number of disposable wipes used and the duration of the decontamination process were recorded for the cost analysis. Results: Both the conventional and the new methods significantly reduced the MRSA detection rate from 68.7% to 12.7% and to 15.3%, respectively ( Conclusion: The one-step method using a combined detergent-disinfectant effectively decontaminated high-touch hospital surfaces in the patient environment while reducing both time and costs. Its broader implementation in local inpatient settings may enhance environmental hygiene while reducing costs.
