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

Circadian rhythms align biological processes with environmental cycles to enhance fitness. Eukaryotic circadian oscillators rely on transcriptional-translational feedback loops, although specific oscillator components vary among lineages. The plant oscillator consists of a uniquely complex network of transcriptional regulators. These clock genes regulate each other's expression and influence key developmental processes such as the transition from vegetative to reproductive growth. Here, we investigate the function of XAP5 CIRCADIAN TIMEKEEPER (XCT), a protein conserved across eukaryotes and previously implicated in RNA processing and circadian regulation in
