Hypophosphatemia: Unraveling a lethal connection with icu mortality in critically ill COVID-19 patients: a multicenter observational 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
Background: Despite a lack of sufficient knowledge about the prevalence and impact of hypophosphatemia in critically ill COVID-19 patients, organ dysfunction, adverse clinical outcomes, and increased mortality have been consistently associated with hypophosphatemia across diverse patient populations. This retrospective, observational study aimed to investigate hypophosphatemia (HypoP) frequency and establish the correlation between variations in serum phosphorus levels and outcomes in critically ill patients with SARS-CoV-2. Methods: The research comprised 205 patients diagnosed with COVID-19 confirmed via RT-PCR. The study included COVID-19 patients who experienced respiratory failure and were in intensive care for more than 24 hours, and their phosphorus values were accurately documented. Clinical para meters, comorbidities, respiratory support requirements, and laboratory findings were analysed. Results: The study participants had a median age of 64 (IQR: 54-75 years), with hypertension being the most pre - valent chronic disease (46%). During the first three days of intensive care, 33% of the participants received conventional oxygen support, whereas 54% required intubation and mechanical ventilation (MV). During this period, hypophosphatemia was noted in 25% of patients, with an ICU admission median serum phosphorus level of 1.02 (0.87-1.25) mmol/L. The median duration of stay in the intensive care unit (ICU) was 7 days, significantly extended in patients with hypophosphatemia (p=0.046). Phosphorus levels on the third day of ICU stay were an independent predictor of ICU mortality. (COX, HR=1.48, 95% CI=1.11-1.98, p=0.006). Conclusions: During the first three days of ICU admission, 25% of SARS-CoV-2 critically ill adult patients presented with hypophosphatemia. This condition was found to increase ICU mortality rates and prolong ICU stays. Therefore, it is crucial to monitor serum phosphorus levels in the care of critically ill COVID-19 patients.
