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

(1) Background: French contrast training (FCT) enhances sports performance, but its long-term efficacy in elite basketball players remains unclear. This study compared FCT and traditional strength training (TST) on jump performance and lower-limb strength. (2) Methods: Sixteen elite basketball players (age 22.4 ± 1.4 years; 14 male, 2 female) were randomly assigned to 8 weeks of FCT (n = 8) or TST (n = 8). The TST protocol consisted of barbell back squat, barbell Bulgarian split squat, conventional deadlift, and barbell hip thrust (4 sets of 8, 6, 4, 4 repetitions at 80%, 95%, 90%, 90% of one-repetition maximum [1RM]; 2-3 min inter-set rest). Assessments included countermovement jump (CMJ) kinetics, CMJ with arm swing (CMJA), running CMJ, running single-leg CMJ, and back squat 1RM, analyzed via repeated-measures ANOVA. (3) Results: A significant Group × Time interaction favored FCT for maximal relative force (
