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

Human-elephant conflict (HEC) is emerging as a growing challenge to biodiversity conservation and rural livelihoods in Asia. Assam's Brahmaputra Flood Plain (BFP)is an important stronghold of the Asian elephant, wherein this study aims to comprehensively analyse the spatio-temporal dynamics of human-elephant conflict BFP, between 2010 and 2024. Using a two-way conflict modelling framework, we examined both human victimization of elephants (EV-HI) and elephant victimization of humans (HV-EI), and integrated these perspectives to identify spatial intersections and temporal patterns of heightened conflict risk. We designed effective risk maps with AUC weighting based on a multi-scale ensemble of five machine learning algorithms (i.e., RF, BRT, SVM, CART, MARS), optimally weighting predictor spatial scales (1-15 km). Conflict incidents exhibited strong seasonality, peaking post-monsoon when major crops such as rice, maize, vegetables, and standing sugarcane are harvested or remain available in the fields. Incidents of conflict have risen significantly after 2017. Spatial analysis revealed that scale-dependent variables, such as orchard cover, forest/population ratio, and edge density, predicted EV-HI risk, whereas landscape heterogeneity, human footprint, and edge density predicted HV-EI risk. We have taken the initiative to combine time dynamics, conflict type correlations, and bivariate hotspot mapping to introduce a new framework that would be concerned not only with risks to human beings but also with risks to elephants. The results are management-friendly and facilitate specific interventions. Our study provides an adaptable decision-support tool that guides crop-switching, early warning alerts, fence evaluations, and corridor restoration. Unlike the usual single-model or one-scale approaches, it integrates multiple perspectives to strengthen conservation planning and promote human-elephant coexistence by protecting both livelihoods and elephant populations.
