Blood glucose kinetics and physiological changes in a type 1 diabetic finisher of the Ultraman triathlon: a case study.
Article in European journal of applied physiology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
purposeTo investigate the blood glucose kinetics and physiological effects experienced by a type 1 diabetic (T1D) finisher of a 3-day, multi-stage ultra endurance triathlon consisting of a 10 km swim and 144.8 km bike (stage 1), a 275.4 km bike (stage 2), and an 84.4 km run (stage 3).
methodsThe athlete self-monitored blood glucose (SMBG) levels via fingerstick blood draw and hand-held glucometer. Researchers evaluated blood glucose kinetics via a continuous glucose monitoring device. The athlete maintained normal dietary and insulin patterns before, during and after competition daily. Weight and body composition were measured via bioelectrical impedance and select biomarkers were measured in blood.
resultsThe athlete spent 73.0, 3.4, and 15.1% of during race time in a hyperglycemic state (≥130 mg dL
conclusionsIt is possible for a T1D athlete to complete a multi-stage ultraendurance triathlon and maintain glycemic control using SMBG methods. In addition, a T1D athlete participating in an ultraendurance triathlon results in substantial changes in body composition, hormones, and muscle damage.
