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

Objective: Examine the longitudinal association between knee pain and prefrailty/frailty. Design: Longitudinal study. Setting: Five clinical centers across the United States. Subject: Data from 3,053 nonfrail participants aged 45-79 years at baseline from the Osteoarthritis Initiative. Methods: According to self-reported knee pain at baseline, the participants were placed into three groups: no knee pain (N = 1,600), unilateral knee pain (N = 822), and bilateral knee pain (N = 631). Frailty status was assessed over time using the five frailty indicators (unintentional weight loss, exhaustion, weak energy, slow gait speed, and little physical activity). Based on the number of frailty indicators present, prefrailty (1-2) and frailty (≥3) were diagnosed. Generalized estimating equations logistic regression analyses were conducted to examine the relationship between knee pain status and prefrailty/frailty. Results: After adjusting for age, sex, race, education, marital status, smoking status, comorbidities, and body mass index, unilateral knee pain at baseline was associated with an increased odds of developing prefrailty (odds ratio [OR] = 1.14, 95% confidence interval [CI] = 1.01-1.27) and frailty (OR = 1.89, 95% CI = 1.38-2.62), and bilateral knee pain at baseline was also associated with an increased risk of prefrailty (OR = 1.41, 95% CI = 1.24-1.62) and frailty (OR = 2.21, 95% CI = 1.63-3.01) over time in comparison with no knee pain. The interaction of knee pain status by time was not significantly associated with either prefrailty or frailty. Conclusions: Knee pain (particularly bilateral knee pain) is associated with an increased risk of developing prefrailty and frailty over time.
