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
Lactate is a food component that is sometimes also used as a food additive. Recent research has reported that lactate may be a crucial signaling molecule and energy substrate. Furthermore, lactate has been suggested to play a crucial role in learning and memory in the brain. It has been reported that high-intensity exercise improves cognitive function via an increase in the blood lactate concentration. However, most studies have focused on the intraperitoneal administration of lactate or on endogenous lactate elevation via high-intensity exercise, rather than on oral intake. Rather than exercise or lactate alone, the combination of the two might further enhance cognitive function. After confirming that 50 mM of lactate (L50) intake alone did not improve cognitive function, we demonstrated that the combination of voluntary exercise and L50 for 4 weeks significantly improved learning and memory in mice, despite the fact that exercise alone did not (
