Following this puts new work involving it at the top of your briefing, with a note saying why it is there. Links are taken from the source record, never inferred.
A cross-sectional survey of clinical practice and implementation challenges with no quantitative comparison group, efficacy data, or primary outcome measure; descriptive in nature and identifying barriers rather than testing an intervention or confirming an effect.
A single case report documenting an uncommon adverse event; provides clinical recognition value but no comparative data or incidence quantification to guide practice.
Single-center retrospective cohort of 21 children describing clinical and genetic spectrum of rare immune dysregulation disorders; descriptive analysis without comparator or control group, providing phenotypic characterization rather than outcome evidence.
A systematic review of heterogeneous observational studies and case series with substantial methodological variation, geographic imbalance, and narrative synthesis only; identifies etiology patterns and barriers but lacks comparative evidence or standardized diagnostic validation to guide practice change.
