Time-series dataset: fondant feeding in overwintering Apis mellifera colonies.
Article in BMC research notes, 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
objectivesWinter mortality of honey bee colonies remains high and reduces early-spring pollination. Fondant feeding is a common emergency intervention, yet quantitative descriptions of colony and microclimate responses-especially homogeneous time-series-are scarce. Milder winters and unstable springs further elevate starvation risk and complicate overwintering. We present a homogeneous time-series dataset that captures the thermal response of overwintering Apis mellifera colonies to fondant feeding under these conditions. The dataset fills this gap and supports reproducible protocols for winter and early-spring fondant feeding. DATA DESCRIPTION: The dataset covers Ukraine (mild winter, unstable spring; one colony) and Canada (record-warm winter; three colonies; four feeding events). Data were collected non-invasively from identical Internet of Things (IoT) hives equipped with internal/external temperature (°C) and relative humidity (%) sensors, a load-cell scale, and a solar-powered acquisition and transmission unit. Measurements were recorded at fixed intervals to ensure homogeneous time series. The repository provides raw and cleaned data, a variable dictionary, cleaning/imputation rules, an event log, and a validation script, enabling quantitative assessment for forecasting colony development and for designing scheduled fondant feeding to help reduce winter losses and prepare colonies for early-spring pollination.
