Immediate Effects of Abdominal Hypopressive Technique Versus PNF Stretching in Shortened Hamstring Syndrome: A Pilot Randomized Controlled Trial.

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
background and purposeShort Hamstring Syndrome (SHS) is described as a deficit of extensibility of this musculature. In contrast to Proprioceptive Neuromuscular Facilitation (PNF), which is widely used in these cases, the abdominal hypopressive technique (AHT) is presented as a possible method to improve flexibility. The primary aim of this trial was to assess the feasibility and acceptability of a single-session AHT program versus PNF stretching in adults with SHS, while the secondary, exploratory aim was to estimate their immediate effects on hamstring flexibility to inform the design and sample size of a future definitive trial.
methodsA pilot randomized controlled trial of a single treatment session was designed, with a pre- and post-treatment evaluation to assess the effects of both techniques on flexibility. 19 subjects were randomized into an AHT group and a PNF stretching group. The Straight Leg Raise and Toe Touch tests assessed changes after treatment. Paired samples t-tests and independent samples t-tests were used to statistically analyze changes within and between groups, respectively.
resultsSignificant improvements were observed in both groups on all tests pre- and post-intervention. However, no significant differences were found between the groups following the intervention. DISCUSSION: Both AHT and PNF techniques produced immediate improvements in hamstring flexibility in adults with shortened hamstring syndrome. However, these findings are exploratory, and, given the pilot nature of the trial, no conclusions can be drawn regarding the superiority of one method over the other.
