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

purposeThis study aimed to develop a rapid spectrophotometric method for counting coccidian oocysts in broilers feces, based on a standard count method "Malassez cell".

methodsTherefore, a raw suspension containing purified oocysts of Eimeria known to parasitize broiler chicken was used. Five concentrations of oocyst suspensions were prepared, and three series of counts using the proposed method were compared with the conventional protocol using Malassez cell to quantify oocysts. Calibration curves were drawn to correlate the specific absorbance measurement at 550 nm and the number of coccidian oocysts quantified using Malassez cell counting (oocysts mL

resultsThe obtained results allowed to establish a formula for an easy estimation of the cell count based on their respective absorbance. The developed method can be used not only for the in vitro evaluation of the anticoccidian activity of natural or synthetic substances, but also for assessing oocysts production and the level of coccidian infection in broilers.

conclusionThe estimation formula has been found to be satisfactory and useful for a wide range of Eimeria oocyst suspension, offering a methodology with high potential for automation in anticoccidian tests in vivo and in vitro.
