1 · What the graph read from it

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 registry

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

backgroundThe kynurenine pathway (KP) plays a pivotal role in many diseases that involve distinct pathological mechanisms.

objectivesSince KP metabolites are potential disease biomarkers, it is crucial to investigate their fluctuations under physiological conditions. As the KP is stress-responsive, this study examines how peripheral KP metabolites change with core temperature increases induced by two different modalities.

methodsIn this randomized cross-over study, 11 young healthy males were subjected to (a) exogenous heating via hot water immersion (44°C, EXO), and (b) exertional heating via exercise (EXE), until rectal temperature (T

resultsEXE and EXO trials induced the KP, but to different extents. Most plasma KP metabolite concentrations (kynurenic acid, picolinic acid, 3-hydrokynurenine, quinolinic acid) increased. Stress markers were elevated in both trials. Changes in KP metabolites, stress, and metabolic markers were not persistent, and returned to baseline following recovery.

conclusionAn elevation in body temperature by heat exposure or exercise increases peripheral concentration of several KP metabolites that return to baseline upon trial cessation, suggesting that KP enzymes are adaptable to physiological stressors.
