Healthcare utilization patterns and medication burden in post-COVID syndrome: a cross-sectional analysis reveals four phenotypes.

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
Post-COVID syndrome has emerged as a major public health challenge, yet comprehensive characterization of healthcare utilization patterns and medication burden within single cohorts remains limited. This cross-sectional analysis examined baseline data from 76 patients (49 ± 12 years, 62% female) enrolled in a randomized trial of psychosomatic treatment interventions for functional post-COVID syndrome. Participants completed the Health Care Utilization Questionnaire (HCU) assessing physician visits, hospitalizations, alternative healing methods, and other healthcare services over the preceding 12 months. Medication and other preparation (MOP) use was systematically documented and classified using the Anatomical Therapeutic Chemical (ATC) classification system. K-means clustering identified distinct patient phenotypes, and correlations between MOP count and healthcare utilization were examined using Spearman correlation coefficients. Healthcare utilization was universal, with 100% of participants engaging with healthcare services and a mean of 43.5 contacts per year. Medication burden was substantial, with 85.5% taking at least one medication, a mean of 4.57 medications per patient, and polypharmacy (≥5 MOP, all types) present in 39.5% of the cohort (46.1% of patients with any MOP). K-means clustering identified four distinct patient phenotypes: Low Utilizers (64.5%,
