8,739 Possible Causes for Heterogeneity

  • Common Cold

    The very high heterogeneity means that the averaged estimates must be viewed with caution.[ncbi.nlm.nih.gov] Heterogeneity was evaluated using the I 2 statistic. When substantial heterogeneity was found ( I 2 40%), subgroup analyses were performed.[dx.doi.org] In addition, we aimed to identify potential sources of heterogeneity in results obtained and to assess their clinical significance.[ncbi.nlm.nih.gov]

  • Russell-Silver Syndrome

    It is suggested that the Russell-Silver syndrome is heterogeneous and that the criteria for its diagnosis need re-evaluation.[ncbi.nlm.nih.gov] The case is another illustration of the genetic heterogeneity of Russell-Silver phenotype.[ncbi.nlm.nih.gov] Clinical presentation is heterogeneous in RSS patients with 11p15 ICR1 hypomethylation.[ncbi.nlm.nih.gov]

  • Generalized Epilepsy with Febrile Seizures Plus

    These results indicate further clinical and genetic heterogeneity in GEFS( ).[ncbi.nlm.nih.gov] Abstract Generalized epilepsy with febrile seizures plus (GEFS ) is a recently recognized but relatively common form of inherited childhood-onset epilepsy with heterogeneous[ncbi.nlm.nih.gov] Abstract Generalized epilepsy with febrile seizures plus (GEFS( )) is an important childhood genetic epilepsy syndrome with heterogeneous phenotypes, including febrile seizures[ncbi.nlm.nih.gov]

  • Urinary Tract Infection

    No significant difference was demonstrated for the outcome of major urological complications (RR 0.72, 95% CI 0.50-1.05), without heterogeneity.[ncbi.nlm.nih.gov] Subgroup analysis and investigation of heterogeneity Issues of heterogeneity were initially explored by between‐study comparisons.[dx.doi.org] Also, our survey showed high heterogeneity in catheter-use practices among French SCs, but offered no data to help determine the best urinary catheterization technique.[ncbi.nlm.nih.gov]

  • Asthma

    Background: Asthma and COPD are heterogeneous diseases. Patients with both disease features (asthma-COPD overlap [ACO]) are common.[ncbi.nlm.nih.gov] Both the Q and I2 statistics indicated a moderate amount of heterogeneity.[ncbi.nlm.nih.gov] Study quality was assessed and results were pooled using fixed effect models or random effect models when moderate between-study heterogeneity was observed.[ncbi.nlm.nih.gov]

  • Chronic Obstructive Pulmonary Disease

    Again, results were heterogenous (I2 59%).[ncbi.nlm.nih.gov] Bronchoscopic thermal vapour ablation therapy in the management of heterogeneous emphysema.[doi.org] We observed significant heterogeneity.[dx.doi.org]

  • Polycystic Ovary Syndrome

    Significant phenotypic and genetic heterogeneity was observed both within and between families.[ncbi.nlm.nih.gov] Because of the heterogeneity among studies, some summarized results should be interpreted with caution.[ncbi.nlm.nih.gov] Significant between-study heterogeneity was detected for several variables assessed.[ncbi.nlm.nih.gov]

  • Kohlschütter-Tönz Syndrome

    The other families, mostly presenting with additional atypical features, were negative for ROGDI mutations, suggesting genetic heterogeneity of atypical forms of the disease[ncbi.nlm.nih.gov] Brief Report Kohlschütter–Tönz Syndrome: Mutations in ROGDI and Evidence of Genetic Heterogeneity Department of Molecular Neuroscience, Reta Lila Weston Research Laboratories[doi.org] Houlden, H ; view all (2013) Kohlschütter-Tönz Syndrome: Mutations in ROGDI and Evidence of Genetic Heterogeneity.[discovery.ucl.ac.uk]

  • Osteoarthritis

    The combined ES in glucosamine hydrochloride (GH) trials was -0.03 (95% CI -0.14, 0.08), with an absence of heterogeneity.[ncbi.nlm.nih.gov] Due to the heterogeneity of the studies, we were unable to perform a best evidence synthesis. However we have provided summaries for each section.[ncbi.nlm.nih.gov] Heterogeneity was tested with Cochran's Q test.[ncbi.nlm.nih.gov]

  • Pneumonia

    There was significant heterogeneity of both sensitivity and specificity according to the Q test, without clear evidence of threshold effect.[ncbi.nlm.nih.gov] DIAGNOSES: The patient had been diagnosed as heterogeneous bullous emphysema pathologically about 3 years ago.[ncbi.nlm.nih.gov] heterogeneity. 20 In light of the heterogeneity of study designs and population characteristics, we calculated the summary effect by means of the DerSimonian–Laird method[dx.doi.org]
