A comparison of change point detection methods for pest outbreak detection.
Article in Environment systems & decisions, 2026. 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
This study evaluates the application of change point detection (CPD) methodologies in the Agricultural Quarantine Inspection Monitoring (AQIM) program to identify significant shifts in pest arrival rates. Unlike prior work that focused on optimizing sampling strategies, this paper emphasizes the numerical evaluation of CPD algorithms for detecting pest outbreaks using AQIM data. The objective is to assess whether these methods can reliably detect and signal outbreaks when pest arrival rates exceed critical thresholds. Through extensive computational experiments, we compare the accuracy, sensitivity, and robustness of CPD methods under various outbreak scenarios and data conditions. The results demonstrate that CPD techniques, particularly cumulative sum (CUSUM) and exponential moving average (EMA), achieve high detection rates and low false alarm rates, even in challenging settings such as small outbreaks. These findings highlight the feasibility of integrating CPD algorithms into AQIM operations, providing a scalable and practical approach to enhancing outbreak detection and strengthening agricultural biosecurity in the context of global trade and evolving pest risks.
