Role of Pain Catastrophizing in the Effects of Cognitive Behavioral Therapy for Chronic Pain in Different Subgroups: An Exploratory Secondary Data Analysis Using Finite Mixture Models.

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
introductionProviding effective treatment for debilitating chronic pain is a challenge among many populations including military service members. Cognitive behavioral therapy for chronic pain (CBT-CP) is a leading psychological pain treatment. Pain catastrophizing is a pivotal mediator of pain-related outcomes. The purpose of this study was (1) to identify patient subgroups who differ in response to CBT-CP and (2) to explore the characteristics that define these patient subgroups. The overall goal was to obtain a better understanding of factors that may influence response to CBT-CP. MATERIALS AND
methodsThis study was a secondary analysis of data from a clinical trial of 149 U.S. active duty service members with chronic pain. Participants underwent group-based CBT-CP for 6 weeks and completed pre- and posttreatment assessments. Finite mixture models were employed to identify subgroups in treatment response, with pain impact score as the primary outcome measure.
resultsWe identified two classes of nearly equal size with distinct pain impact responses. One class reported improved pain impact scores following CBT-CP. This improvement was significantly associated with lower (better) baseline depression scores and greater improvement in posttreatment pain catastrophizing. In contrast, the other class reported slightly worse mean pain impact scores following CBT-CP treatment; this response was not related to baseline depression or change in pain catastrophizing.
conclusionsOur findings demonstrate that a sizable proportion of individuals with chronic pain may not respond to group-based CBT-CP and may require a more individualized treatment approach.
