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

Purpose: Knee extensor strength is a critical factor in patients with knee osteoarthritis. However, no studies have investigated whether knee extensor strength directly affects patient-reported outcomes after open-wedge high tibial osteotomy (OWHTO). The purpose of this study was to investigate the association between knee extensor strength and patient-reported outcomes after OWHTO. Methods: Patients who underwent OWHTO between 2016 and 2023 with knee function test results 12 months after surgery were included in this study. Isokinetic knee extensor strength was measured on the involved and uninvolved limb and normalised to body weight (KES/BW). Patient-reported outcomes were assessed using the International Knee Documentation Committee (IKDC) subjective scores. Pearson correlation analysis and multivariable linear regression analysis were used to determine whether KES/BW on the involved limb was related to the IKDC subjective score. Results: Fifty-eight knees from 52 patients who received OWHTO were evaluated. Pearson correlation analysis showed that KES/BW on the involved limb was significantly associated with the IKDC subjective score in OWHTO ( Conclusions: KES/BW on the involved limb was independently associated with the IKDC subjective score at 12 months after OWHTO. This metric should be considered to achieve better patient-reported outcomes after OWHTO. Level of Evidence: Level IV.
