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

backgroundIn basketball, most studies analysing seasonal variations in neuromuscular performance through vertical jump testing rely solely on the countermovement jump (CMJ), a slow stretch-shortening cycle (SSC) test. This study aimed to analyse early-season changes in jumping performance in highly-trained youth basketball athletes, utilizing a comprehensive jump test battery to determine the time-course of adaptations in concentric-only qualities (using the squat jump, SJ), and slow (through the CMJ) and fast SCC function ( MATERIALS AND

methodsTwenty-six players (under-16:

resultsSJ and CMJ height improved only from T1 to T2 (both

conclusionsReactive strength qualities and fast SSC performance peaked during the early in-season, while changes in concentric-only and slow SSC function (assessed with SJ and CMJ, respectively) occurred exclusively during the pre-season.KEY MESSAGESDifferent vertical jump tests showed distinct early-season changes in youth basketball.Squat (SJ) and Countermovement Jump (CMJ) performance improved only during the pre-season, while reactive strength qualities assessed via the Drop Jump (DJ) and Repeated Jumps peaked during the early in-season.DJ reactive strength index and ground contact times might be more sensitive than CMJ or SJ height to detect changes in neuromuscular capabilities in-season.
