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

objectivesManaging severe pneumonia remains a challenge. Rapid diagnostic tests, such as multiplex polymerase chain reaction (mPCR), facilitate quick microorganism identification and may enable timely and appropriate antimicrobial therapy. However, studies from low-income countries are scarce. This study aimed to evaluate the diagnostic characteristics of mPCR and its impact on antibiotic therapy and outcomes in critically ill patients with pneumonia.

designMulticenter observational study.

settingTwelve ICUs across Morocco. PATIENTS: Adult patients with pneumonia requiring invasive mechanical ventilation, including community-acquired pneumonia (CAP), hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP).

interventionsNone. MEASUREMENTS AND MAIN

resultsRespiratory samples were analyzed using both mPCR and conventional microbiological methods. The diagnostic performance of mPCR was evaluated, including its sensitivity and specificity. Additionally, the appropriateness of mPCR-induced modifications in empiric antibiotic therapy and their impact on patient outcomes were assessed. A total of 210 patients were included, with a median age of 50 years (range, 33-67 yr), of whom 66.2% were male. Pneumonia types were distributed as 30% CAP, 58% VAP, and 12% HAP. mPCR demonstrated a sensitivity of 96.9% (95% CI, 92.3-99.2%) and a specificity of 92% (95% CI, 91-93%). Following mPCR, antibiotic therapy modifications were observed in 58% of patients (n = 122), including de-escalation or cessation in 11% (n = 23), escalation in 26.5% (n = 56), adequacy adjustments in 7.5% (n = 16), and initiation of antibiotics in 13% (n = 27). The appropriateness of antibiotic therapy increased significantly from 38.7% (n = 83) to 67% (n = 141; difference, 27.5%; 95% CI, 18.3-36.7; p < 0.0001). Generalized mixed model analysis revealed that appropriate post-mPCR antibiotic therapy was associated with reduced mortality (adjusted odds ratio, 0.37; 95% CI, 0.15-0.93; p = 0.038).

conclusionsOur findings suggest that the use of mPCR is associated with a significant improvement in the appropriateness of empiric antibiotic therapy and is also associated with a positive impact on the outcome of patients with pneumonia.
