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 ecological role of horizontal gene transfer within biofilms has been recently investigated, and it has been reported that conjugation directly induces bacteria to form biofilms via expression of conjugative pili. In this report, we described the contribution of bacterial conjugation during biofilm formation by Escherichia coli harboring a natural IncF conjugative F plasmid (F(+)). We showed that cell-to-cell pili interactions through the homosexual mating-pair formation among F(+) × F(+) cells (namely, F(-) phenocopy phenomenon) promote E. coli biofilm formation at the early development stage. The presence of F(+) × F(+) population is the result from heterogeneity within biofilms leading to sessile bacteria that grow at different rates, in which the late-stationary phase cells acted as F(-) phenocopy cells. According to global transcriptional analysis, the biofilm lifestyle shared similar gene expression pattern with F(-) phenocopies. F(-) phenocopy cells expressed specific sets of chromosomal genes (e.g., genes for general stress response and two-component systems) that control the regulation regions of F transfer operon by blocking surface exclusion proteins and DNA transfer machineries. However, mating-pair proteins were stabilized and consequently promoted F(+) × F(+) pili assembly. Thus, F(-) phenocopy phenomenon is an effective adaptive behavior of bacterial cells during biofilm formation.
