The Association Between Patient Characteristics and Pain, Physical Function, and Quality of Life Among Patients with Hip Osteoarthritis: Explorative Study with Data from a Randomized Controlled Trial.

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: Hip Osteoarthritis (OA) is a degenerative joint disease associated with pain, reduced physical function, and impaired quality of life (QoL). Identifying patient characteristics associated with these outcomes may improve understanding of disease impact and support individually tailored treatment. Purpose: To explore associations between patient characteristics and key outcomes of pain, physical function, and QoL among individuals with hip OA. Secondarily, to investigate differences in pain, physical function, and QoL between patients recruited from hospitals and physiotherapy clinics in Denmark. Study design: Explorative cross-sectional study, with baseline data from a randomized controlled trial. Methods: Baseline data from The Hip Booster Trial was analyzed, including 159 adults with clinically diagnosed hip OA recruited from physiotherapy clinics and hospitals in Denmark. Associations between BMI, physical activity, age, sex, symptom duration, analgesic use (yes/no), muscle power (watts), educational level, and patient reported outcomes (HOOS pain, ADL, QoL) and the 30s-Chair Stand Test (CST) were evaluated using multiple linear regression. Change in the independent variable required to achieve a minimal important difference (MID) was calculated. Results: Of the eight characteristics investigated, two were associated with all key outcomes. Higher muscle power was associated with less pain (0.08 points, 95% CI 0.02; 0.13), better QoL (0.05 points, 95% CI -.01; 0.11), and better physical function; HOOS ADL (0.10 points, 95% CI 0.04; 0.16), 30s-CST (0.02 repetitions, 95% CI 0.01; 0.03). The use of analgesics was associated with worse HOOS pain (-10.99 points, 95% CI -15.66; -6.31), worse HOOS QoL (-7.89 points, 95% CI -13.30; -2.49), and poorer physical function measured by HOOS ADL (-8.25 points, 95% CI -13.63; -2.86), and 30s-CST (-.76 repetitions, 95% CI -1.84; 0.32). Conclusion: Greater muscle power was associated with better outcomes for HOOS Pain, QoL, ADL, and the 30s-CST, whereas use of analgesics was negatively associated with these outcomes.
