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
Detection of Legionella pneumophila serogroup 1 urinary antigens is the most widely used technique for the diagnosis of Legionnaires' disease (LD). The aim of this study was to evaluate the performance of the Legionella K-set® immunochromatographic test, in comparison with the BinaxNOW® Legionella urinary antigen card (UAC) on concentrated urine samples (US). A total of 250 concentrated US including 200 prospective US sent to the laboratory for urinary antigens' testing and 50 frozen US from patients with confirmed LD were tested. Positive US were retested after boiling (5 min, 100 °C). Each US leading to discordant results between the two tests was further tested using Binax™ Legionella EIA. Then, 10 additional positive non-concentrated US were tested using both tests. On concentrated US, Legionella K-set® test showed concordant results with that of BinaxNOW® Legionella. All negative US with BinaxNOW® were negative with Legionella K-set® test. For the 50 frozen US, all were positive with BinaxNOW® and 49 were positive with Legionella K-set®, all confirmed after boiling except 3 US which led to uninterpretable results with Legionella K-set®, due to a migration defect. Three of the 10 additional positive non-concentrated US were found negative with Legionella K-set® and only 1 US remained negative after concentration. All these positive non-concentrated US were positive with BinaxNOW® Legionella. The performance of the Legionella K-set® test is comparable to that of BinaxNOW® Legionella UAC, if performed on concentrated US.
