Prognostic signature of multimorbidity, geriatric syndromes and resources cluster in older in- and outpatients: a pooled secondary analysis with a 6-month follow-up.

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
objectiveThe prognosis of older adults is strongly influenced by the relation of multifactorial geriatric syndromes (GS) and their health-maintaining counterparts, geriatric resources (GR). The present analysis aimed to identify clusters of comorbidities, GS and GR, and to measure their multidimensional prognostic signature in older patients admitted to different healthcare settings.
designPooled secondary analysis of three longitudinal interventional studies with the 3- and 6-month follow-up data collection on mortality and rehospitalisation.
settingInpatients in an internal medicine ward (n=495), inpatients in an ageing medicine ward (n=123) and outpatients from a general practice (n=105).
participantsA total of 734 patients with multimorbidity who aged over 60 years were recruited between August 2016 and July 2020 (mean age 77.8 years, SD 6.2 and 43% female). OUTCOME MEASURES: Comprehensive Geriatric Assessment (CGA), including Cumulative Illness Rating Scale (CIRS), 17 GS and 10 GR, and the CGA-based Multidimensional Prognostic Index (MPI) as a measure of multidimensional prognosis and frailty were assessed. Based on a general linear model and a hierarchical clustering method, clusters of comorbidities, GS and GR were obtained.
resultsThe study identified five clusters of GR-related GS, namely, psychosocial, iatrogenic, neurovegetative, sensorimotor and fluid dysbalance, along with two clusters related to GR, focusing on independence achievement and requirements- circumstances. Additionally, two clusters were identified pertaining to the CIRS, encompassing sensory-vegetative and heart-kidney morbidity. Patients within the iatrogenic cluster exhibited significantly higher MPI and readmissions during follow-up compared with those outside this cluster (p<0.001). Furthermore, membership in the fluid dysbalance or psychosocial cluster was associated with a significantly increased mortality rate during follow-up (p<0.001).
conclusionsA feasible combination of GR and GS in clinical routine enables the identification of clusters with clear prognostic relevance, which may improve prognosis through tailored treatment. TRIAL REGISTRATION NUMBERS: DRKS00010606/DRKS00013791/DRKS00017094
