Research on association analysis between electricity consumption behaviors and weather factors based on mapreduce.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The change of weather factors will lead to great changes in users' electricity consumption behaviors. In order to discover the associations between users' electricity consumption behavior and weather factors, and meet the needs of efficient mining of massive data, in this paper a parallel association rule mining method is presented based on MapReduce. Firstly, to convert electricity data into the form suitable for association rule mining, the density-based K-means method is implemented to discretize the electricity consumption data, in which the parallel calculation method of sample density is presented. Then the cluster results are combined with the weather data. Next, the parallel frequent itemset mining method and association rule mining method are designed and implemented based on Apriori. In the frequent itemset mining MapReduce job the Combiner function is added and implemented. The local support threshold is set in the Combiner implementation to filter out some candidate itemsets, thereby reducing the time to transmit data among slave nodes. Finally, experiments on a Hadoop cluster are conducted. The experimental results validate availability and scalability of the proposed method.
