Trial reportBrazilian journal of physical therapy
Is outcome observed in performance of clinical tests associated with patient-reported outcome measures after patellofemoral pain treatment? Secondary analysis of data from a randomized clinical trial.
Trial report in Brazilian journal of physical therapy. 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
backgroundClinical functional tests for patellofemoral pain (PFP), such as step-up, step-down and squat, are commonly used in clinic practice, although the extent to which changes in these tests reflect changes in patient-reported outcome measures (PROMs) remains unclear.
objectiveInvestigate how changes in step-up, step-down, and squat tests are associated with changes in PROMs in individuals with PFP.
methodsThis secondary analysis used data from a randomized controlled trial (N = 218) comparing 12-week outcomes following either foot orthoses or 4-week hip exercise program. The number of pain-free repetitions in the functional tests of step-up, step-down and squat was assessed. PROMs included the Kujala, the Knee Injury and Osteoarthritis Outcome Scale (KOOS) subscales (Symptoms, Pain, Activities of Daily Living, Sporting and Recreation and Quality of Life (QoL), and the Global Rating of Change (GROC). Associations between change scores (differences between follow-up and baseline) in pain-free repetitions in the clinical functional tests and PROMs were analyzed using multivariate regression and binary logistic regression for dichotomized GROC (p < 0.05).
resultsData was available for 157 participants. There was a positive association between change scores in functional tests and PROMs, with explained variances ranging from 11 to 30%. The step-up test was weakly to moderately associated with KOOS Symptoms, Pain, QoL and Sport/Recreation. Step-down was associated with Kujala and KOOS Sport/Recreation. The squat test was not associated with any PROM.
conclusionsImprovement in step-up test is associated with better PROMs. Clinicians might use the step-up test to monitor progress in individuals with PFP.
