Nutritional strategies for noninvasively ventilated critically ill patients: results from the NUTRINIV retrospective study.
Article in BMC nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06260202 (Nutrition Under Noninvasive Ventilation in Critically Ill Patients), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundThe ideal nutritional strategy for patients on noninvasive ventilation (NIV) remains uncertain. This study assessed the nutritional management of intensive care unit (ICU) patients undergoing NIV, evaluating discrepancies between actual intake and recommended targets. Associations between different nutritional modalities and patient outcomes were also analyzed.
methodsThis retrospective study analyzed electronic records of adults undergoing NIV for more than two days in the ICU from March 1, 2020, to February 1, 2023. Data included nutritional management, NIV settings, and patient outcomes. Daily caloric and protein gaps were calculated as the difference between actual intakes and targets determined using the ESPEN stepwise approach. Descriptive statistics and tests were used to assess differences in nutrition modality. Univariable and multivariable Cox regression models were applied to examine associations between nutritional variables and outcomes.
resultsRecords from 92 patients (62 males, 67%) with a median (Q1; Q3) age of 67 (59; 75) years were analyzed. Nutrition began a median of 1 (0; 2) day after NIV initiation and lasted for a median of 4 (2; 8) days. Enteral nutrition (EN) was provided to 10% of patients, parenteral nutrition (PN) to 43%, and both modalities to 23%, while 24% received oral nutrition. Median caloric intake in the ICU was 8.9 (4.2; 11.8) kcal/kg/day, and protein intake was 0.4 (0.1; 0.5) g/kg/day. Although mean (SD) daily caloric intake increased from 102.9 (257.7) kcal on day 1 to 726.2 (597.6) kcal on day 8, up to 90% of patients still failed to meet the recommended caloric intake targets. Patients on PN or combined nutrition achieved higher caloric and protein intakes but were associated with longer NIV durations (p < 0.001). Multivariable analysis showed that the peak daily caloric intake during ICU stay was independently associated with lower ICU mortality.
conclusionsThis study highlights that critically ill patients undergoing NIV received sub-target caloric and protein intake, despite early initiation of nutritional support. Patients receiving PN or combined modalities achieved higher nutritional intakes but had longer NIV durations. An association was observed between higher peak daily intake and lower mortality, but not between days below target and adverse outcomes.
