Test-Retest Reliability of Maximal and Rapid Knee Extensor Force Production: Influence of Verbal Instruction and Trial Selection Criteria.
Article in Scandinavian journal of medicine & science in sports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Reliable assessments of maximal and rapid muscle strength are essential for evaluating neuromuscular performance and adaptations. This study examined the effects of verbal instruction and trial selection criteria on performance outcomes and intersession test-retest reliability during maximal isometric knee extensor testing. Twenty-three physically active, healthy adults completed three separate test sessions, performing isometric knee extensor contractions under three standardized verbal instructions: Hard and Fast (HF; "as hard and fast as possible"), Fast Only (FO; "as fast as possible"), and Hard Only (HO; "Gradual increase in force"). Rate of torque development (RTD) and impulse were calculated using three selection criteria: the trial with the highest peak torque (Max_Peak_Torque), the trial with the highest 200-ms impulse (Max_Impulse200), and the highest value for each time interval (Max_Composite_Interval). Both FO and HF instructions demonstrated good-to-excellent reliability, reflected by intraclass correlation coefficients (ICC) and within-subject coefficients of variation (CV
