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

backgroundThere is a lack of evidence about the tolerance of enteral nutrition (EN) in COVID-19 critically ill patients. However, several gastrointestinal manifestations related to COVID-19 have been described. The aims of this study were to analyze the incidence of gastrointestinal intolerance (GI) associated to EN (diarrhea, vomiting, gastroparesis and constipation) and to describe energy/protein provision along with biochemical alterations during the first week of EN.

methodsA retrospective cohort of COVID-19 critically ill patients under mechanical ventilation. We reported daily enteral nutrition infusion and gastrointestinal manifestations within the first week of intubation and enteral nutrition initiation.

resultsFifty-two patients were included; 40.3% were overweight and 46.2% were obese. During the first 7 days of EN, manifestations of GI intolerance such as vomiting, diarrhea and gastroparesis were present in 18 patients (32.4%). Hypernatremia (39%) was the most frequent electrolyte abnormality. Only Acute Kidney Injury (AKI) diagnosis was associated with a higher energy deficit on day 7. No associations between drug prescription and GI intolerance were observed. On day 4, 94.5% of patients were receiving more than 80% of energy requirements and 94.2% of protein requirements. Accumulated energy and protein deficits at day 3 were 2171.2 ± 945 kcal and 114.9 ± 49.2 g, respectively; and 2586.4 ± 1151 kcal, 133.3 ± 60.4 g at day 7.

conclusionEnteral nutrition is feasible and well-tolerated in COVID-19 patients with mechanical ventilation within the first week of enteral nutrition initiation. More studies are needed to elucidate the impact of nutritional therapy on infection course and outcomes.
