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

objectivesTo examine the anticipatory effect on lower extremity muscle activation during single leg drop landing and jumping.

methodsSeventeen healthy males performed single leg drop landing and jumping, under conditions manipulating the subsequent movement after landing. Participants performed the anticipated condition (subsequent movement-land/jump-was preplanned), followed by the unanticipated condition (subsequent movement was given via visual signals). Electromyography of the gluteus medius (GM), rectus femoris (RF), vastus medialis (VM), semitendinosus (ST), biceps femoris (BF), tibialis anterior (TA), and medial gastrocnemius (MG) were obtained. The time of onset, time-to-peak amplitude (from onset or initial contact), and peak amplitude were compared (p<0.05).

resultsOverall, under the unanticipated condition, the time (0 = initial contact) of onset of RF (-101 ms vs. -245 ms), TA (-116 ms vs. -232 ms) and MG (-122 ms vs. -180 ms) and time-to-peak amplitude (from initial contact) of RF (223 ms vs. 13 ms), ST (111 ms vs. -9 ms), and MG (79 ms vs. -41 ms for unanticipated and anticipated, respectively) were delayed compared to anticipated condition.

conclusionsWhen visual cues were unanticipated, participants demonstrated delayed and redistributed muscle activation timing during single leg landing and jumping.
