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

objectiveThe objective of this study was to estimate the minimal important change (MIC) and minimal clinically important difference (MCID) for pain and physical function in individuals with hip osteoarthritis (OA) following a physiotherapist-guided exercise intervention.

methodsSecondary analysis from a randomized controlled trial of 196 adults with hip OA allocated one of two nine-month exercise programs. Patient-reported outcomes measures for hip pain severity (Numeric Rating Scale [NRS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] pain subscale) and physical function (WOMAC physical function subscale, Patient-Specific Functional Scale [PSFS]) were collected at baseline and three and nine months. Global ratings of change in pain and physical function at three and nine months served as anchors.

resultsMIC estimates were 2.1 and 2.4 points for NRS pain at three and nine months, respectively; 2.8 and 3.0 points for WOMAC pain at three and nine months, respectively; 8.7 and 8.3 points for WOMAC physical function at three and nine months, respectively; and -2.1 and -2.0 points for PSFS at three and nine months, respectively. The MCID estimates were 2.0 and 2.4 points for NRS pain at three and nine months, respectively; 2.8 and 3.0 points for WOMAC pain at three and nine months, respectively; 9.2 and 8.3 points for WOMAC physical function at three and nine months, respectively; and -3.5 and -0.7 points for PSFS at three and nine months, respectively.

conclusionThis study provides robust, context-specific MIC and MCID estimates for outcomes in hip OA following exercise. These values can inform the interpretation and design of exercise-based clinical trials for hip OA.
