Respiratory management of critically ill pneumocystis pneumonia patients: a multicenter retrospective study.

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.
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
backgroundPneumocystis jirovecii pneumonia (PjP) is a rising cause of acute respiratory failure in immunocompromised patients, often requiring Intensive Care Unit (ICU) admission. However, optimal ventilatory strategies remain unclear.
methodsFor the present study, we conducted an ancillary analysis of the PRONOCYSTIS study, a large multicenter cohort of PjP patients. Patients admitted to the ICUs were compared according to initial respiratory management (High-Flow Nasal Cannula (HFNC), standard Oxygen (SO) or Non-Invasive Ventilation (NIV). A propensity score adjustment [inverse probability of treatment weighting (IPTW) analysis] was implemented to account for potential confounders. The primary outcome was intubation rate. Univariable and multivariable Cox regressions were also used to assess variables associated with survival.
resultsOver the study period, 248 patients with PjP were included in the present analysis. Of those, 70 were treated by HFNC while 118 and 60 received SO and NIV, respectively. HFNC patients had a decreased intubation rate (28.6% versus 45.0% in NIV and 55.4% in SO patients; p = 0.003). When assessing the impact of respiratory management on intubation by IPTW, HFNC remained an independent protective factor (weighted Hazard Ratio (HR) 0.41 (95% CI 0.24-0.69); p < 0.001). While, NIV was not associated with intubation (HR 0.62 (95% CI 0.37-1.02); p = 0.056). Through adjusted survival analysis, long-term corticosteroids treatment (aHR 4.03 (95% CI 2.01-8.08); p < 0.001), Solid tumor (aHR 3.37 (95% CI 1.45-7.86); p = 0.005) and the Sequential Organ Failure Assessment score (aHR 1.24 (95% CI 1.15-1.35); p < 0.001) were found to be independent predictor for death. Initial respiratory support was not associated with survival either in the Cox multivariable analysis or in the IPTW analysis.
conclusionThrough this multicenter observational study of severe PjP patients, although oxygenation strategy was not associated with D90 survival, HFNC support appeared to be associated with a lower intubation rate. Further prospective studies are warranted to refine respiratory management in critically ill PjP patients.
