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
The conserved band-interband pattern is thought to reflect the looped-domain organization of insect polytene chromosomes. Previously, we have shown that the chromodomain protein Chriz and the zinc-finger protein Z4 are essentially required for the maintenance of polytene chromosome structure. Here we show that both proteins form a complex that recruits the JIL-1 kinase to polytene chromosomes, enabling local H3S10 phosphorylation of interband nucleosomal histones. Interband targeting domains were identified at the N-terminal regions of Chriz and Z4, and our data suggest partial cooperation of the complex with the BEAF boundary element protein in polytene and diploid cells. Reducing the core component Chriz by RNAi results in destabilization of the complex and a strong reduction of interband-specific histone H3S10 phosphorylation.
