Does Recalibration Response Shift Alter Perceived Treatment Effects in Patient-Reported Outcomes After Anterior Cruciate Ligament Reconstruction?
Article in Orthopaedic journal of sports medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Background: Patient-reported outcome measures (PROMs) are used longitudinally after anterior cruciate ligament reconstruction (ACLR). However, PROM scores depend on patients' perspectives, which are likely to change over time, particularly after a health-related event. This phenomenon, known as recalibration or "response shift," may limit our ability to accurately interpret PROMs. Purpose: To identify whether recalibration response shift effects are present in PROM scores after ACLR and to investigate the influence of coping styles and life events on outcomes and recalibration response shift after ACLR. Study Design: Cohort study; Level of evidence, 2. Methods: Patients having primary ACLR were recruited to complete the Knee injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentation Committee Subjective Knee Form (IKDC SKF) preoperatively and 1 and 2 years postoperatively. At both postoperative time points, patients completed a second KOOS and IKDC SKF based on their recollection of preoperative status, as well as brief COPE (Coping Orientation to Problems Experienced) and life event questionnaires. Unadjusted change (traditionally measured change), adjusted change (accounting for the patient perspective), and the magnitude of the recalibration response shift (the difference in change scores) were calculated for all outcomes, along with the proportion of patients exhibiting meaningful positive recalibration, meaningful negative recalibration, or no meaningful recalibration. Linear regression analyses evaluated the influence of coping strategies and life events on postoperative PROM scores and the magnitude of recalibration response shift. Results: Of 171 participants (mean age, 24 years, 56% male), 158 (92%) and 146 (85%) completed 1 and 2 years follow-up, respectively. Adjusted change was significantly greater than unadjusted change ( Conclusion: A meaningful recalibration response shift was clearly identified in IKDC SKF and KOOS scores 1 and 2 years after ACLR. Traditional within-patient change scores do not reflect participants' perceived change in constructs after ACLR, and recalibration response shifts may alter perceived treatment effects (both over- and underestimation).
