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
backgroundAflatoxins are the most extensively studied group of mycotoxins produced by molds, especially the Aspergillus group, which are highly toxic to animals and humans.
objectivesSince immunoassay is a simple and rapid method for the analysis of many toxic substances in comparison to the chromatographic methods, it is necessary to produce specific and sensitive antibodies for detection of Aflatoxin M1 (AFM1). The current study was conducted to produce bioconjugate of Aflatoxin M1 (AFM1) with Bovine Serum Albumin (BSA) as well as to generate specific antibodies against AFM1 for immunoassay of the mycotoxin. MATERIALS AND
methodsFirst, AFM1 was converted to AFM1-(O-carboxymethyl) oxime derivative. Then, AFM1-oxime was coupled with BSA and the product was assessed by UV-VIS spectrophotometry. In order to generate polyclonal antibodies against AFM1, rabbits were immunized with BSA-AFM1 conjugate. Produced antibodies were purified using ion exchange chromatography and BSA-Sepharose 4B affinity chromatography. The titers and specificity of the produced antibodies were determined by Enzyme-Linked Immunosorbent Assay (ELISA).
resultsThe results indicated that coupling of AFM1 with O-(Carboxymethyl) hydroxylamine hemihydrochloride was suitable and 12 moles of AFM1-oxime were successfully coupled to each mole of BSA. In addition, the titers and specificity of the prepared antibody were considerable compared to standard anti-AFM1 antibodies. The relative cross-reactivity of each toxin (relative to AFM1) with purified anti-AFM1 antibodies, as determined by the amount of aflatoxin necessary to cause 50% inhibition of enzyme activity, was 70, 105, 240, and 2500 ng/mL for AFB1, AFB2, AFG1, and AFG2, respectively.
conclusionsThe prepared antibody can be used for the development of an ELISA kit to assay AFM1 in milk and other biological fluids.
