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

purposeTo investigate the effects of anterior cruciate ligament (ACL) reconstruction on mechanical and contractile properties of the skeletal muscles of the lower extremities in soccer players through tensiomyography (TMG).

methodsAll soccer players with acute ACL tear included underwent resting TMG assessment of muscles of both lower extremities before and 1 year after ACL reconstruction. The muscles assessed were vastus medialis (VM), vastus laterals (VL), rectus femoris (RF), semitendinosus (ST), biceps femoris (BF), gastrocnemius medialis (GM), and gastrocnemius lateralis (GL). The TMG parameters obtained for each muscle were maximal displacement (D m), delay time (T d), contraction time (T c), sustained time (T s), and half-relaxation time (T r).

resultsThe injured leg had a significant decrease in VL-T c, ST-T c, GM-T c, GL-T r, and GL-T d, and a significant increase in VM-T r and GM-T s in the postoperative compared to preoperative period. The non-injured leg demonstrated significant preoperative-postoperative changes in the VL, RF, and BF, but not in VM, ST, GM, and GL The magnitude of preoperative-postoperative differences in the injured leg was significantly higher in RF-T c, ST-T c, BF-D m, and GL-T r, but lower in RF-T r and GM-T s, compared to the non-injured leg. Both groups improved their symmetry between the quadriceps and hamstring muscle groups in both sides.

conclusionsThe quadriceps muscles improved their resistance to fatigue and contraction velocity in both sides, and the hamstring muscles improved their contraction velocity and muscle tone in both sides as well. Improvements in contraction velocity and muscle tone were more evident in the quadriceps and hamstrings of the injured compared to the uninjured side. In addition, the intervention increased the percentage of symmetry between both sides in the TMG of the quadriceps muscles and the balance between ACL-agonist (hamstrings) and ACL-antagonist (quadriceps) muscle groups in both sides. This study shows how ACL reconstruction (and subsequent rehabilitation) can positively impact neuromuscular characteristics of the quadriceps and hamstrings. LEVEL OF EVIDENCE: Therapeutic, Level II.
