1 · What the graph read from it

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.

2 · The registry

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

backgroundFrequent testing for Legionella concentration in water is required by most health risk monitoring organizations worldwide. Domestic hot water and cooling tower water networks must be regularly controlled to prevent Legionnaires' disease, a potentially deadly lung infection. MICA Legionella is the fastest culture-based detection method for all serogroups of Legionella pneumophila, with automatic enumeration in 48 h and no need for confirmation.

objectiveThis study compares the performance and robustness of MICA Legionella with the reference method ISO 11731:2017 for the enumeration of culturable L. pneumophila.

methodsMICA Legionella and ISO 11731:2017 results were compared for domestic hot water and cooling tower water. Inclusivity and exclusivity were tested on reference and environmental strains. Ruggedness, lot-to-lot consistency, and stability of the reagents kit were also studied.

resultsEnumeration of L. pneumophila by MICA Legionella was statistically equivalent to ISO 11731:2017 in both matrixes. In cooling tower waters, MICA Legionella showed better sensitivity than ISO 11731:2017. It presented a 94% sensitivity and a 97% specificity.

conclusionMICA Legionella is a highly sensitive and specific method for culturable L. pneumophila enumeration. It presents, in 48 hours, equivalent or better results than ISO 11731:2017. Its protocol is robust to variations. Its reagents kit is stable for up to 18 months. HIGHLIGHTS: MICA Legionella is a robust and reliable method for the enumeration of culturable L. pneumophila in domestic and cooling tower water. It reduces significantly the number of sample pretreatments required in ISO 11731:2017. Automatic identification and enumeration of L. pneumophila microcolonies eliminates the requirement to have skilled analysts and limits the results variability. It also greatly reduces the time to results to 48 h instead of 7-10 days with ISO 11731:2017 while providing statistically equivalent results.
