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

The growing wealth of single-cell omics datasets presents unprecedented opportunities to uncover new insights into temporal gene dynamics during development. However, this relies on accessible, diverse time-series data and robust in-silico analysis methods-resources that are underutilized in current databases. Herein, we present TEDD 2.0 ( https://tedd.obg.cuhk.edu.hk/ ), an enhanced version of our Temporal Expression during Development Database, featuring advanced in-silico tools to characterize developmental lineages, investigate functional roles of temporally regulated genes, and compare developmental mechanisms across diverse species and life stages. This database integrates over 15 million cells from nine species, spanning 81 tissue-types and 42 time points, with three new analytical modules offered through an easy-to-use interface with dedicated cloud-based computational resources: (i) virtual gene knockout to assess transcriptome-wide responses to gene perturbation and their functional consequences; (ii) cross-species integration which minimizes species and data batch effects to reveal evolutionarily conserved and divergent temporal gene expression patterns; and (iii) trajectory inference and marker gene analysis to infer developmental lineages and detect marker genes relevant in cell fates decisions. Overall, this database provides researchers with a powerful platform to explore the temporal expression patterns of target genes, decipher finer regulation of developmental mechanisms, and guide both research design and discovery across development.
