Seven years of time-tracking data capturing collaboration and failure dynamics: the Gryzzly dataset.
Article in Scientific data, 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
We introduce the Gryzzly time-tracking dataset: a longitudinal, high-resolution collection of 4.4 million interactions recorded between 12,447 users and 173,323 tasks across 50,759 projects, spanning from 2017 to 2024. Compiled from real-world usage data of the Gryzzly software, the dataset encompasses projects from diverse industries such as marketing, finance, and banking. It provides a detailed view of daily activities contributing to project completion, including information about the users involved, the tasks they worked on, and the planned versus actual costs of each project. To validate the published data, we analyzed the underlying temporal collaboration network, revealing expected patterns such as circadian user activity, power-law characteristics in degree distributions, and heterogeneously distributed inter-declaration times. Additionally, we observed well-documented failure dynamics, including a heavy-tailed distribution of failure streak lengths and diverging performance improvement trends between successful and failed projects. These features make the Gryzzly dataset a key resource for studying productivity, team dynamics, and project failure.
