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
Marine anammox bacteria have been an exciting research area in recent years due to their high effectiveness in treating ammonia-containing saline wastewater. However, their direct implementation in the wastewater industry faces challenges due to slow growth, difficulty obtaining pure cultures, and their tendency to exist as part of an anammox consortium, interacting symbiotically with other bacteria. In the present study, 91 draft genome metagenome-assembled genomes (MAGs) from a long-term-operated reactor were recovered to clarify detailed symbiotic interactions within an anammox consortium. One marine anammox bacterial MAG, identified as Candidatus Scalindua, was successfully recovered and was abundant within the sampled microbial community. A comprehensive metabolic pathway ana-lysis revealed that Ca. Scalindua exhibited the complete anammox pathway and the Wood-Ljungdahl pathway for carbon fixation. The folate biosynthesis pathway in Ca. Scalindua was incomplete, lacking dihydrofolate reductase, a key enzyme for tetrahydrofolate (THF) production. The folate biopterin transporter, essential for transporting folate-related metabolites among coexisting bacteria, was identified exclusively in Ca. Scalindua. In addition, the impact of exogenously supplied THF on microbial activity and carbon uptake rates was investigated in batch experiments using
