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

Transportation of Cryptosporidium oocysts in river type source water is of great concern in an area where extensive human activities exist. In this study, a total of 47 samples were collected from Tongxiang, China, where drinking source water was taken from a complicated river network system, by three sampling campaigns over a rainy season in 2009, to reveal the presence, genotypes, and likely source of Cryptosporidium oocysts in river water. Immunofluorescence microscopy analyses show that 37 (78.7%) were Cryptosporidium positive, with a mean concentration of 0.51 oocysts per liter. These results suggest that the protozoa were commonly distributed in the river network type source water of Tongxiang with a relatively low concentration level. PCR analysis was used to determine the species/genotypes of Cryptosporidium, which revealed the presence of the animal related species/genotypes including Cryptosporidium suis, Cryptosporidium fragile, and the avian III, pig II, cervine genotypes. Three of them were also detected in wastewater samples taken from neighboring animal farms, showing that farm animals rather than human might be the major pollution sources. This is the first report on simultaneous detection and genotyping of Cryptosporidium oocysts from surface water in China.
