The Phospho-Code Determining Circadian Feedback Loop Closure and Output in Neurospora.
Article in Molecular cell, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 45 papers.
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
In the negative feedback loop driving fungal and animal circadian oscillators, negative elements (FREQUENCY [FRQ], PERIODS [PERs], and CRYPTOCHROMES [CRYs]) are understood to inhibit their own expression, in part by promoting the phosphorylation of their heterodimeric transcriptional activators (e.g., White Collar-1 [WC-1]-WC-2 [White Collar complex; WCC] and BMAL1/Circadian Locomotor Output Cycles Kaput [CLOCK]). However, correlations between heterodimer activity and phosphorylation are weak, contradictions exist, and mechanistic details are almost wholly lacking. We report mapping of 80 phosphosites on WC-1 and 15 on WC-2 and elucidation of the time-of-day-specific code, requiring both a group of phosphoevents on WC-1 and two distinct clusters on WC-2, that governs circadian repression, leading to feedback loop closure. Combinatorial control via phosphorylation also governs rhythmic WCC binding to the promoters of clock-controlled genes mediating the essential first step in circadian output, a group encoding both transcription factors and signaling proteins. These data provide a basic mechanistic understanding for fundamental events underlying circadian negative feedback and output, key aspects of circadian biology.
