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

purposeThis study aimed to evaluate the modulation and reliability of the vastus medialis (VM) and vastus lateralis (VL) H-reflexes in both passive and active conditions.

methodsRecruitment curves of VM and VL H-reflexes and M-waves at rest and during muscle contraction (30% of maximal voluntary contraction) were performed for 12 healthy males and were then repeated after 1 h, 1 day and 1 week. The maximal H-reflexes of each muscle were normalized to their respective maximal M-waves (H/M ratio) and absolute (CV) and relative (ICC) reliability were calculated.

resultsThe H-reflex was potentiated in active compared to passive condition and a higher H-reflex occurrence (12 vs. 10 subjects) and amplitude (≈+150%) was found for the VM compared to the VL in active condition. The intra- (ICChour = 0.97) and inter-day (ICCday = 0.92; ICCweek = 0.92) reliability was poor for the passive VM H/M ratio due to high within-subject variations (CVhour = 52.2%; CVday = 69.8%; CVweek = 60.9%) whereas for the active condition the reliability, especially intra-day, was good (ICChour = 0.93 and CVhour = 12%; ICCday = 0.86 and CVday = 14.5%; ICCweek = 0.79 and CVweek = 19.7%).

conclusionsThis study showed differential modulation of the H-reflex between vasti muscles of the quadriceps and a higher occurrence and reliability for the active VM H-reflex. One can therefore conclude that it seems more appropriate to evoke quadriceps VM H-reflex (rather than VL) during an isometric muscle contraction.
