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 registryThe 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.

6 · The paper itselfAbstract
Small-dose electrolyte additives are widely used to enhance battery performance, yet rational additive selection for the stabilization of lithium metal (Li°) electrodes remains challenging. Coulombic efficiency (CE) measurements in asymmetric Li°||Cu° cells serve as critical evaluative metrics, but the resulting CE values often deviate from expectations based on additive structure alone. Herein, we delve into the design of fluorinated electrolyte additives by combining statistical analysis of Li°||Cu° cycling data with compositional characterization as well as atomistic and chemical simulations. Our results demonstrate that nonafluorobutanesulfonyl fluoride, as an electrolyte additive, induces only a marginal effect on the Aurbach CE values during short-term cycling tests of Li°||Cu° cells. Intriguingly, during extended-cycling, statistical analysis reveals that the same additive exhibits divergent effects in electrolyte families based on bis(trifluoromethanesulfonyl)imide (TFSI
