Left atrial functional changes following short-term exercise training.
Trial report in European journal of applied physiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 2 of them syntheses 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
backgroundExercise-induced adaptations of the human atria remain understudied, particularly early in the training process. We examined the effects of short-term high-intensity interval training (HIT) and continuous moderate-intensity training (CMT) on left atrial (LA) systolic and diastolic function, relative to left ventricular (LV) function in young, healthy men, by speckle tracking echocardiography (STE).
methodsFourteen untrained men (mean age = 25 ± 4 years) were randomized to HIT or CMT, and assessed before and after six training sessions over a 12-day period. HIT included 8-12 intervals of cycling for 60 s at 95-100% of maximal aerobic power (VO₂MAX), interspersed by 75 s of cycling at 10 % VO₂MAX. CMT consisted of 90-120 min of cycling at 65% VO₂MAX.
resultsVO₂MAX increased following HIT and CMT by 11.5 and 5.5%, respectively (p < 0.05). Calculated plasma volume expanded 11 % following HIT and 10% following CMT (p < 0.005). Resting LV volumes and ejection fraction were unaltered following training. Peak atrial longitudinal strain increased following HIT (41.8 ± 5.2%-47.1 ± 3.7%, p < 0.01) and CMT (38.5 ± 4.6%-41.7 ± 6.0%, p < 0.01). Atrial systolic strain rate increased following HIT (1.6 ± 0.2%/s-2.0 ± 0.3%/s, p < 0.01) and CMT (1.6 ± 0.2%/s-1.9 ± 0.2%/s, p < 0.01).
conclusionsLA function assessed by STE improves rapidly during short-term intensive exercise training.
