Objectives: Immunosuppressive therapies for the treatment of patients with systemic sclerosis (SSc) and SSc related interstitial lung diseases (SSc-ILD) include cyclophosphamide (CYC), mycophenolate mofetil (MMF), azathioprine (AZA) and methotrexate (MTX). The objectives were to compare and rank these therapies in term of forced vital capacity (FVC) % predicted, diffusing capacity of the lung for carbon monoxide (DLco) % predicted and adverse events (AEs).Methods: We present pooled estimates of mean difference (MD) and odds rates (ORs) with 95% confidence intervals (CIs) among different therapies. We also ranked these agents with surface under the cumulative ranking probability (SUCRA).Results: CYC plus AZA had the highest SUCRA probability (70%) on reducing risk of the deterioration of FVC compared with CYC, observation (OBS), MMF and AZA. While for the prevention of the deterioration of DLco, MMF showed the highest SUCRA probability (76%) compared with others. Moreover, AZA showed the lowest probability (32%) for AEs among active interventions.Conclusions: CYC plus AZA was the preferred immunosuppressive strategies compared to others on preventing the deterioration of FVC. MMF resulted with the highest probability as the best in preventing the deterioration of DLco. Monotherapy of AZA was less pulmonary function benefit but related less AEs.

Comparative Excretory Systems

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.

Comparing the Survival Analysis of Two or More Groups

Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Lung Capacity01:47

Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Survey Safety01:28

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Self-Efficacy

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...
