Prevalence of Varroa destructor Infestations in Apis mellifera Honeybee Colonies and Associated Risk Factors in Ankasha District, Northwest Ethiopia.

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
backgroundVarroa destructor is an ectoparasite of broods and adult stages of honeybees, which gradually leads to colony losses worldwide, both directly (feeding on fatty tissue) and indirectly (disease transmission).
objectivesThe objectives of this study were to determine the prevalence of varroosis and to identify possible risk factors for the occurrence of varroosis.
methodsThe honeybee colonies were selected by a simple random sampling method from each apiary of 90 volunteer apiarists. Combs containing mature drone broods were taken out of each colony and examined for the presence of V. destructor on the brood and in the cell. A cross-sectional study design was used for data collection. The data were analysed by chi-square test (χ
resultsOverall, 66.15% of honeybee colonies were infested with V. destructor. Colony strength, colony age and agro-ecology had statistically significant (p < 0.05) associations with the occurrence of varroosis. Weak colonies were 4.89 (p < 0.001) times more likely to be at risk to varroosis than moderate colonies. Likewise, honeybee colonies with the age of 2-3 years and >3 years were 1.99 and 4.74 (p < 0.001) times more likely to be at risk to varroosis than colonies with <2 years, respectively. Furthermore, honeybee colonies in highland and midland agro-ecologies were 3.67 and 5.07 (p < 0.001) times more likely at risk to infestation of varroosis when compared with colonies from lowland agro-ecologies, respectively.
conclusionVarroosis is prevalent in the study area, which alarms the starting of an effective control option to save honeybee colonies.
