Lower respiratory tract infection treatment guided by procalcitonin

A living systematic review

Clinical summary: This meta-analysis suggests that clinical intervention is not effective when the analysis is restricted to trials in which at lesat 75% of subjects had lower respiratory tract infection. In addition, meta-regression suggests that increased compliance with the procalcitonin protocol within a trial correlates with less benefit. Lastly, in most trials, the quality of care in the control group had not been optimized. Heterogeneity of results as measured by I2 may 'not be important' at 0%. This review updates the previously published meta-analysis.(1)

Methods overview: This repository is an openMetaAnalysis that combines methods of scoping, rapid, and living systematic reviews. This analysis updates one or more previously published review(s).(1) A comparison of studies include in this review compared to prior reviews are in the table, reconciliation of trials included with prior meta-analyses/. Newer studies included are listed in the references below. Rationale for newer trials excluded may be listed at the end of the references.

  • Inclusion criteria for studies: we included trials included by either of the two reviews by Scheutz et al below. ** We excluded trials in which less than 75% of patients had lower respiratory tract infection.
  • Methods for openMetaAnalysis
  • Evidence search for this review

Results: Details of the studies included are in the:

The forest plot for the primary outcomes are below. Additional forest plots of secondary analyses may be available. Principle results

The meta-regression for the primary outcomes are below. Additional meta-regressions of secondary analyses may be available. Principle results for benefit
