Challenges in Diagnosing Acanthamoebae Infections Using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry.

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
Acanthamoebae are amphizoic protozoa that can be human pathogens, causing diseases such as granulomatous amoebic encephalitis or Acanthamoeba-keratitis; Therefore, it is critical to have a rapid and reliable diagnostic approach; Following two studies with divergent results, we have aimed to assess the development of a time-saving and cost-effective method for medical parasitological diagnostics to identify Acanthamoebae by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry based on their characteristic protein profiles. Several xenically cultured Acanthamoeba strains were applied; To eliminate the impact of proteins derived from nutrition bacteria, UVC inactivation, heat inactivation, and centrifugal membrane filtration were tested. The achieved mass spectra turned out to be not reproducible in our study; In conclusion, the establishment of a method for the characterization of Acanthamoebae by MALDI-ToF MS was not achieved, and therefore, the method represents, to date, no suitable alternative to the real-time polymerase chain reaction in medical diagnostics of Acanthamoebiasis.
