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
Introduction: Micronutrients are key regulators of human metabolism and influence time to recovery and post-COVID complications. In this study, we aimed to assess the prevalence of micronutrient deficiency and its association with the severity of post-COVID musculoskeletal manifestations. Materials and Methods: This cross-sectional observational study was conducted in a tertiary care center. The study was registered in the Clinical Trial Registry of India (CTRI number: CTRI/2022/07/044336) Patients aged 18-65 years attending the post-COVID clinic with musculoskeletal manifestations were included. Patients' demographics, personal habits, and clinical history specific to the course of COVID-19 were collected and a physical examination was performed. Blood samples were collected to assess iron, selenium, zinc, and copper, and complete blood picture with differential count and C-reactive protein (CRP) assay. Musculoskeletal manifestations during the post-COVID phase (within a year after the COVID-19 infection) such as fatigue, myalgia, arthralgia, myositis, fibromyalgia, and arthralgia were documented. Copper and zinc levels were analysed at the National Institute of Nutrition and all other parameters were analysed in our institute. Continuous data expressed as mean, and standard deviation, and analysed by independent Results: The data collected from 166 individuals were analyzed, and micronutrient deficiencies were observed in 66 (39.7%) for iron, 43 (25.9%) for selenium, 30 (18.07%) for copper, and 7 (4.2%) for zinc. Multivariate analysis showed the presence of arthritis was negatively correlated with serum selenium levels ( Conclusion: Our research found a significant association between micronutrient deficiency of iron, copper, and selenium with the severity of musculoskeletal manifestations in the post-COVID-19 phase. A 40% prevalence of at least one micronutrient deficiency was observed in our study population which comprised of patients with musculoskeletal manifestations in the post-COVID-19 phase.
