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.

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.

Abstract

objectivesThis study compared the acute effects of static stretching (SS) and the Mulligan bent leg raise (BLR) technique on hamstring flexibility and jumping performance in asymptomatic young adults.

methodsForty-two participants with bilateral hamstring tightness were randomly assigned to the SS or BLR group (n = 21 each). Active knee extension (AKE), vertical jump (VJ), and single-leg hop (SLH) performance were assessed before and immediately after a single intervention session.

resultsA significant main effect of time was found for all outcomes (p < 0.05). Significant time × method interactions were observed for AKE and SLH, but not for VJ. The BLR group showed greater improvements in hamstring flexibility (AKE: +6.38°) compared with the SS group (+2.10°). SLH performance improved more in the BLR group, whereas VJ improvements were similar between groups. After adjusting for baseline AKE differences, post-intervention AKE remained significantly higher in the BLR group.

conclusionBoth SS and BLR produced beneficial acute effects on hamstring flexibility and jumping performance. BLR demonstrated larger acute improvements in hamstring flexibility and single-leg hop performance in this sample; however, these findings should be interpreted cautiously and may not be directly generalizable to athletic populations. CLINICALTRIALS: gov ID: NCT07138950.
