A real result from a sound single-centre study showing a new diagnostic method with performance comparable to qPCR, but in a descriptive rather than interventional context and without evidence of clinical outcome impact.
Rigorous comparative diagnostic study with large sample size, pre-specified endpoints (essential and categorical agreement), and clear superiority in time-to-result; well-designed but a diagnostic accuracy study rather than a clinical outcome trial.
First descriptive report of HCV genome sequencing and resistance patterns in an Indian cohort; uncontrolled, hospital-based study with small sample and no comparator arm, useful for surveillance but insufficient to guide treatment decisions.
Diagnostic validation study in an outbreak setting with modest sample size and primarily descriptive molecular findings; detects pathogen DNA but lacks clinical outcome data or comparative diagnostic accuracy metrics.
In vitro susceptibility surveillance from a large multicenter collection in immunocompromised patients; establishes baseline resistance patterns and comparative agent activity but lacks clinical outcome data, treatment efficacy, or validation in patient populations.
Single-center proof-of-concept validation of a machine-learning classifier for antimicrobial resistance prediction using MALDI-TOF spectra, with internal hold-out testing only and no external validation, before clinical application.
A single-centre diagnostic accuracy study of moderate size with sound methodology but surrogate endpoints (categorical agreement, MIC prediction) rather than clinical outcomes, showing the NMIC-150 system performs comparably to reference broth microdilution for ESBL detection.
Rigorous point-prevalence survey with molecular and culture confirmation, multivariable regression analysis, and clinical outcome follow-up in a defined high-endemic population, establishing significant associations between rectal carriage and mortality/morbidity with reported effect sizes and confidence intervals.
