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
Recirculating aquaculture systems (RAS) for Atlantic salmon (Salmo salar L.) are closed-containment systems (CCS) offering biosecure, water-efficient farming conditions, yet pathogen transmission remains a critical concern. While horizontal transmission in water is well-documented in RAS, the potential for aerosol-mediated transmission remains underexplored. The current study was conducted at two commercial Faroese Atlantic salmon RAS smolt farms. At Smolt farm 1, aerosolised pathogens were monitored using two aerosol samplers (Coriolis+ and Coriolis Compact, Bertin Technologies SAS, France), along with water and fish swab samples, to evaluate pathogen dynamics. A sequential infection pattern was observed, beginning with salmon gill pox virus (SGPV), followed by non-virulent infectious salmon anaemia virus (ISAV-HPR0), piscine orthoreovirus-1 (PRV-1), and sporadic detections of infectious pancreatic necrosis virus (IPNV) and Flavobacterium psychrophilum. All pathogens were detected in aerosol samples, with the highest detection rates and pathogen loads at the biofilter room compared to the local tank degassers. Detection trends for SGPV and ISAV-HPR0 in aerosols reflected those in fish and water samples. Coriolis+ performed marginally better compared to Coriolis Compact in reflecting the infection dynamics. Viable IPNV was not isolated from initial aerosol samples at Smolt farm 1, though bacterial culture identified relevant colonies for Atlantic salmon RAS. Targeted aerosol sampling for IPNV at Smolt farm 2 post IPNV outbreak produced IPNV-specific cytopathic effects in cell lines from Coriolis Compact aerosol samples, marking the first field-based evidence of viable aerosolised IPNV from a RAS. The current study extends our previous work by introducing anaesthetic water as a refined, non-invasive surveillance method, whilst providing the first field-based evidence of Atlantic salmon viruses in RAS aerosols, which signals the potential for airborne transmission and emphasises the need for strict biosecurity measures.
