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
backgroundPhysiological tremor is known to increase following intense exercise due to neuromuscular fatigue and altered sensorimotor control. While cryotherapy is widely used in sports medicine to modulate peripheral excitability and afferent feedback, its potential role in attenuating exercise-induced tremor has not been directly examined. This study investigated whether targeted cryostimulation of myofascial trigger points (MTrPs) can modulate lower-limb physiological tremor in adolescent swimmers.
methodsThirty-four competitive adolescent swimmers completed a randomized counterbalanced crossover trial involving two conditions: 60-s localized cryostimulation of identified MTrPs and a control condition without intervention. Tremor of both lower limbs was recorded using accelerometry at baseline and after a standardized 7-min recovery period following a 30-s maximal tethered swimming test. Log-transformed tremor spectral power [L(2-5 Hz), L(9-14 Hz)] and tremor frequency parameters [F(2-5 Hz), F(9-14 Hz)] were analyzed using repeated-measures ANOVA.
resultsExercise increased tremor spectral power, whereas MTrP cryostimulation attenuated the post-exercise response in the 9-14 Hz frequency band (Condition × Time interaction, p = 0.010). The modulatory effect was observed predominantly in tremor spectral power, whereas frequency outcomes were more heterogeneous: F(2-5 Hz) did not show a consistent overall post-exercise shift, whereas F(9-14 Hz) increased following exercise and remained lower in the cryostimulation condition.
conclusionsTargeted pre-exercise localized cooling of MTrPs may partially modulate selected post-exercise neuromuscular responses in adolescent swimmers, particularly within the 9-14 Hz tremor frequency band, although the functional relevance of these effects for sport-specific performance remains to be established.
