A structural equation modeling approach to understanding physical function of terminal cancer 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
purposeUnderstanding the activities of daily living (ADL) of cancer patients at the end-of-life stage may help healthcare providers develop interventions for preserving physical function and enhance patient's dignity in an everyday care context. This study aims to develop and test a causal effect model of physical function in terminal cancer patients.
methodsA total of 238 participants were recruited from two hospitals in South Korea. The data were collected using a structured questionnaire including demographics, visual analogue scale for pain, Functional Assessment of Chronic Illness Therapy-Fatigue, and Katz index of independence in ADL. The collected data were analyzed using SPSS WIN 25.0 and AMOS 23.0 programs for structural equation modeling procedures.
resultsMost participants were aged 65 years or older (65.5%), male (53.8%), and inpatients (74.4%). The most common primary cancer site was gastrointestinal tract (44.1%). Physical function of the participants was positively influenced by regular exercise and negatively influenced by hospitalization, fatigue, and pain, explaining 35.1% of the variance. In this study, regular exercise improved participants' ADL level directly and indirectly either by reducing fatigue or decreasing fatigue through controlling pain. Pain did not affect ADL directly but decreased ADL level indirectly through fatigue as a mediator.
conclusionADL was positively influenced by regular exercise and was negatively influenced by hospitalization, fatigue, and pain. Based on these results, in order to minimizing the problems of physical function in terminal cancer patients, interventions that reduce pain and fatigue and provide regular exercise are required.
