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

objectiveTo examine use, costs, and value of physical therapy (PT) among subgroups.

designWe conducted an observational study of data from a randomized trial of a pain coping skills intervention. Good and poor outcome subgroups were determined based on Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC) Pain and Physical Function scores. The use and costs of PT care as well as changes in WOMAC Pain and Physical Function scores over 4 time periods during a 1-year follow-up were reported. We compared the number of PT visits, total PT costs, and cost per 1-unit improvement in WOMAC scores for the 2 latent subgroups.

participantsPatients who catastrophized about their pain prior to knee arthroplasty (N=384).

interventionsPain coping skills training, arthritis education, and usual care.

main outcome measuresThe WOMAC Pain Scale was the primary outcome.

resultsThe value of PT was lower and the cost of PT was higher for poor vs good outcome subgroups beginning 2 months after knee arthroplasty. For example, during the 2- to 6-month period, participants in the poor outcome subgroup incurred a PT cost of $5181.22 per 1-unit improvement in WOMAC Pain compared with $437.87 per 1-unit improvement in WOMAC Pain for the good outcome subgroup (P<.001). From the 6- to 12-month period, WOMAC scores worsened for the poor outcome subgroup, indicating no benefit from PT.

conclusionsPatients in 2 latent classes demonstrated clinically important differences in value of PT. Future research should identify rehabilitation-based interventions that reduce utilization and enhance effectiveness for patients at high risk for poor outcome.
