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
Neural proliferation zones mediate brain growth and employ Delta/Notch signaling and HES/Her transcription factors to balance neural stem cell (NSC) maintenance with the generation of progenitors and neurons. We investigated Notch-dependency and function of her genes in the thalamic proliferation zone of zebrafish larvae. Nine Notch-dependent genes, her2, her4.1-4.5, her12, her15.1-15.2, and two Notch-independent genes, her6 and her9, are differentially expressed and define distinct NSC and progenitor populations. her6 prominently executes patterning information to maintain NSCs and the zona limitans intrathalamica Shh signaling activity. Surprisingly, simultaneous deletion of nine Notch-dependent her genes does not affect NSCs or progenitor formation, and her4 overexpression only caused reduction of ascl1b progenitors. Combined genetic manipulations of Notch-dependent and -independent her genes suggest that her6 in the thalamic proliferation zone prominently maintains NSCs and inhibits NSC-to-progenitor lineage transitions. The her gene network is characterized by redundant gene functions, with Notch-independent her genes better substituting for loss of Notch-dependent her genes than vice versa. Together, her gene regulatory feedback loops and cross-regulation contribute to the observed robustness of NSC maintenance.
