A Comparison of the Effects of the Timing of Resistance Exercise on Glucose Levels Within the Target Range in People With Type 1 Diabetes (TREX Study): A Randomized Crossover Trial.
Trial report in Diabetes/metabolism research and reviews, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
aimThe purpose of this paper is to examine the acute and nocturnal glycaemic response to morning fasted, fed or afternoon fed resistance exercise in people with type 1 diabetes.
methodsIn a crossover RCT, people with type 1 diabetes performed three acute bouts of resistance exercise in (1) morning (8 AM-10:30 AM) in a fed state, (2) morning (8 AM-10:30 AM) in a fasted state and (3) afternoon (3-8 PM) in a fed state, with interstitial glucose levels measured 6-h post-exercise and in the nocturnal period (11 PM-6 AM).
resultsIn all participants (n = 66), mean glucose levels were lower in the 6-h period after afternoon fed versus morning fasted resistance exercise (9.46 ± 2.56 vs. 8.65 ± 2.04 mmol/L, P = 0.04), with no other differences noted. In multiple daily injections (MDI), users (n = 47), but not insulin pump users (n = 19), in the 6-h period post-exercise mean glucose levels were higher (9.63 ± 2.58 vs. 8.44 ± 1.93 mmol/L, P = 0.007), time-in-range (3.9-10.0 mmol/L) lower (50.9 ± 29.5% vs. 67.0 ± 27.6%, P = 0.007) and time above range (> 10.0 mmol/L) higher (44.4 ± 32.1% vs. 26.3 ± 25.3%, P = 0.003) in morning fasted versus afternoon fed state; no other differences were noted.
conclusionResistance exercise timing and feeding status (fed vs. fasted) independently influence post-exercise glycaemic responses in people with type 1 diabetes. Performing resistance exercise in the afternoon under fed conditions was associated with a more favourable glucose profile, particularly among MDI users. These findings indicate that consideration of both time of day and feeding status is important when optimising resistance exercise prescription in this population.
