1 · What the graph read from 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.

2 · The registry

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

Maximal intended velocity (MIV)-based resistance training enhances explosive performance, yet it remains unclear whether different MIV modalities induce distinct neuromuscular adaptations. This study compared the effects of two-way ballistic (TWB) and jump squat (JS) training on explosive strength and neuromuscular characteristics in highly trained sprinters. Forty highly trained male sprinters (Tier 3) were randomly assigned to TWB (n = 20) or JS (n = 20). Both groups completed 12 training sessions (5 sets of 8 repetitions at 50%-55% 1RM) over 6 weeks. Pre- and post-tests included countermovement jump (CMJ), consecutive CMJ (CCMJ), 30-m sprint, isometric mid-thigh pull (IMTP), 6-s cycle sprint, vastus lateralis (VL) muscle architecture, and VL and biceps femoris (BF) activation during CCMJ performance. Both groups improved CMJ, CCMJ height, 30-m sprint, and 6-s cycle performance (p < 0.05), with similar increases in VL muscle architecture. TWB showed a greater IMTP 100-ms impulse improvement (ηp
