Detection of Giardia and Cryptosporidium in environmental matrices with immunomagnetic separation: two or three acid dissociations.

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
This study evaluated the technology of detection of Giardia spp. cysts and Cryptosporidium spp. oocysts in environmental matrices obtained after water treatment on a bench scale. Calcium carbonate flocculation with immunomagnetic separation was the selected method to quantify the protozoa, and the importance of the number of acid dissociations in the immunomagnetic separation was assessed. When adding the third acid dissociation, an increase of 71% ± 6 in floated residue and 31.9% ± 28.7 in filter backwash water in cyst recovery was observed, while in oocyst recovery, a non-significant increase was detected. In the filtered water, this increased dissociation was important in the protozoa recovery with increases greater than 33%. The results showed that there is a strong interaction of these target organisms with the magnetic microspheres, since protozoa were still recovered in the third acid dissociation and some of them were still adhered to the magnetic microspheres.
