The efficacy of an intervention can be assessed by randomizing to different diagnostic testing strategies and solving simultaneous equations: Required when assessing the effectiveness of test, trace and isolation

  title={The efficacy of an intervention can be assessed by randomizing to different diagnostic testing strategies and solving simultaneous equations: Required when assessing the effectiveness of test, trace and isolation},
  author={H. Llewelyn},
The efficacy of an intervention can be assessed by randomising patients to different diagnostic tests instead of to an intervention and control. This is based on a familiar view that treatment will be more effective if given to patients based on the results of appropriate diagnostic tests (i.e. the correct diagnosis) than if it given to those based on the results of inappropriate tests (i.e. the wrong diagnosis). The tests must have different characteristics e.g. sensitivities with respect to… Expand

The distributions of the candidate gold standard test results in those with and without the required outcome of treatment are used with Bayes rule to create curves that are used to identify a cut-off point for offering a treatment to a patient and also to inform the patient's decision to accept or reject the suggested treatment.

The Predictive Approaches to Treatment effect Heterogeneity (PATH) Statement
The goal of predictive HTE analysis is to provide patient-centered estimates of outcome risks with versus without the intervention, taking into account all relevant patient attributes simultaneously, to guide future analyses and reporting of RCTs. Expand
Mathematical analysis of the diagnostic relevance of clinical findings.
The process of diagnosis by elimination in terms of probabilities is analysed mathematically and inadequate evidence may be identified, new tests developed, and their effectiveness assessed in a logical and efficient way. Expand
Personalized evidence based medicine: predictive approaches to heterogeneous treatment effects
Fundamental conceptual problems with the prediction of outcome risk and heterogeneity of treatment effect (HTE) are reviewed, as well as the limitations of conventional (one-variable-at-a-time) subgroup analysis. Expand
Regression discontinuity was a valid design for dichotomous outcomes in three randomized trials.
It is concluded that the RD design provides similar but substantially less precise treatment effect estimates compared with an RCT, with local regression being the preferred method of analysis. Expand
How different urinary albumin excretion rates can predict progression to nephropathy and the effect of treatment in hypertensive diabetics
The data demonstrate that irbesartan is effective in reducing the onset of nephropathy within two years when the pre-treatment AER is above 40 µg/minute, but if the A ER is below this level it progresses unusually to nephopathy withinTwo years. Expand
Implication of backward contact tracing in the presence of overdispersed transmission in COVID-19 outbreaks.
Backward contact tracing can be an effective tool for outbreak control, especially in the presence of overdispersion as was observed with SARS-CoV-2. Expand

Commentary: the birth of microalbuminuria: a milestone in the history of medicine.
This work has shown that microalbuminuria predicts mortality in non-insulin-dependent diabetes mellitus and clinical proteinuria in maturity-onset diabetes, and a comparison of neurological functions in blood sugar groups suggests that the former is more predictive of mortality than the latter.

The effect of irbesartan on the development of diabetic nephropathy in patients with type 2 diabetes.
Irbesartan is renoprotective independently of its blood-pressure-lowering effect in patients with type 2 diabetes and microalbuminuria, and serious adverse events were less frequent among the patients treated with the drug. Expand
