1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundPneumonia is a leading cause of ICU admission and mortality, requiring prompt and adequate antimicrobial therapy to improve outcomes. Conventional cultures are slow and often insensitive, delaying targeted treatment. Syndromic PCR panels offer rapid identification of pathogens and resistance genes directly from respiratory samples, potentially improving early antibiotic optimization. However, the true clinical benefit of these diagnostics in critically ill patients remains uncertain.

methodsWe conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing PCR-based molecular diagnostics with standard culture techniques in predominantly adult ICU patients with severe community-acquired, hospital-acquired, or ventilator-associated pneumonia. Literature searches were performed in PubMed, Embase, and Cochrane CENTRAL from inception to July 16, 2025. The primary outcome was in-hospital mortality. Secondary outcomes included adequacy of initial antimicrobial therapy and time to effective antibiotic administration. Data were synthesized using random-effects models.

resultsWe included five randomized controlled trials comprising 2,466 patients. Syndromic PCR testing did not significantly reduce in-hospital mortality, the primary outcome (RR 1.04; 95% CI: 0.90–1.21; p = 0.57; I² = 0%). However, PCR testing was associated with a higher rate of adequate initial antimicrobial therapy (RR 1.82; 95% CI: 1.10–3.00; p = 0.02; I² = 97%) and a reduction in time to effective antibiotic administration (mean difference − 27.98 h; 95% CI: − 46.07 to − 9.89; p = 0.002; I² = 94%).

conclusionsSyndromic PCR diagnostics did not reduce in-hospital mortality in critically ill patients with pneumonia but were associated with improved adequacy of initial antimicrobial therapy and faster initiation of effective treatment. These findings support their role as a complementary tool in ICU-based antimicrobial stewardship.
