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
Background: Frequently touched objects within hospital premises acts as a potential reservoir for healthcare-associated infections (HCAIs), significantly amplifying the risk when biofilm-producing bacteria are involved. These bacteria often exhibit multidrug-resistant (MDR) patterns, complicating the antimicrobial treatments. So, this study intended to determine the bacterial contamination level on frequently touched objects and their antibiotic susceptibility patterns and to determine the relation between biofilm-producing Methods: A hospital-based cross-sectional study was conducted at different intensive care units (NICU and MICU) and operation theatre of Frontline Hospital, Kathmandu, Nepal. Aseptically, 297 swab samples were collected and cultured, and the isolated bacteria were identified using standard microbiological procedures. Antibiotics susceptibility test done by the Kirby-Bauer disc diffusion method, and biofilm detection was done by the microtiter plate method at 570 nm by using an ELISA reader. For data analysis, SPSS Version 23 was used. Results: Of total 297 swab samples processed, 31.3% (93/297) showed bacterial growth, yielding a total of 108 isolates. Mixed growth was reported on 16.1% (15/93) samples. The frequency of Gram-positive and Gram-negative bacteria was 95.4% (103/108) and 4.6% (5/108), respectively. The main isolates were coagulase-negative staphylococci (CoNS) 50.9%, followed by Conclusion: A frequently touched object within different intensive care units and operation theatre was found to be contaminated with potential pathogens and normal flora. Bacterial contamination of such objects can contribute to HCAIs and the hands of health professionals can be the mode of cross-contamination.
