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 (1) investigate how lower limb strength, vertical jump metrics, and patient reported outcome measures (PROMs) change in the initial 3- to 12-months of recovery following ACLR; and (2) explore which strength and vertical jump metrics best differentiate between lower and higher Knee Osteoarthritis Outcome Score (KOOS) and Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) scores.

methodsThirty recreationally active athletes undergoing unilateral primary ACLR underwent field-based assessments of knee flexion and extension strength, hip adduction and abduction strength, and double and single leg countermovement (CMJ) and drop vertical jump (DVJ) kinetics at 3-, 6-, 9- and 12-months following surgery. The KOOS and ACL-RSI were also completed. Mixed models were used to investigate how measures of lower limb strength, vertical jump metrics and PROMs change across the first 12-months of rehabilitation. Mixed model decision trees were used to determine which strength and vertical jump measures best discriminated between lower and higher PROMs.

resultsVertical jump height and reactive strength index (RSI) improved significantly over time (p < 0.001), with reductions in contraction and contact times (p < 0.05). Isometric knee extension and eccentric knee flexion strength increased significantly (p < 0.001), as did KOOS and ACL-RSI scores (p < 0.001). Surgically reconstructed limbs displayed deficits in most vertical jump and strength measures compared to the uninjured contralateral limb, although deficits reduced over time with between limb asymmetry deceasing in 70% of these variables (p range: 0.05 to <0.001). Single leg CMJ jump height < 8.4 cm best discriminated between lower and higher ACL-RSI scores (r

conclusionMost measures of lower limb strength and vertical jump metrics change in both the ACLR and uninjured contralateral limbs across the first 12-months of recovery following primary ACLR. A strong relationship was found between measures of lower limb strength and vertical jump performance with PROMs. LEVEL OF EVIDENCE: Level II, lower quality prospective cohort study.
