Validation of the Patient Activation Measure in kidney stone disease patients.

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
introductionWe aimed to validate the Patient Activation Measure (PAM) within a kidney stone disease (KSD) population, determine the variability of patient activation within this population, and characterize relationships between activation and variables such as health literacy, quality of life, and demographics.
methodsThis cross-sectional study includes individuals 18 years or older followed for KSD at University of Montreal Hospital Center. Demographic data and responses for the PAM, Wisconsin Stone Quality of Life scale, and Health Literacy Questionnaire (HLQ) were acquired.
resultsFemales and those with poor medication adherence were found to have significantly lower activation. The HLQ dimensions "Actively managing my health," "Navigating the healthcare system," and "Understand health information well enough to know what to do" were associated with significantly higher activation. Rasch analysis revealed an item reliability of 0.81, a person reliability of 0.98, and a Cronbach's alpha of 0.88. Regarding item fit, only item 1 (When all is said and done, I am the person who is responsible for taking care of my health) fit poorly with the model. Principle component analysis revealed evidence of a second dimension, accounting for 9.0% of the variation in observed responses.
conclusionsFemale sex and poor medication adherence were associated with significantly lower activation. Aspects of health literacy concurring with the precise definition of "activation" were associated with significantly higher PAM scores. The PAM was found to have good person and item reliability, and good internal consistency; however, principal component analysis revealed that construct validity is possibly threatened by multidimensionality.
