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
backgroundAcute respiratory distress syndrome (ARDS) is a serious condition frequently encountered in intensive care units (ICUs) and is associated with high morbidity and mortality. Regional data are crucial for optimizing diagnosis and management, particularly in infection-prevalent regions like Central India.
objectivesThis study aimed to evaluate the clinicoetiological profile of ARDS patients and assess the prognostic value of Sequential Organ Failure Assessment (SOFA) scores at admission and 48 hours.
methodsThis prospective observational cohort study included 100 adults who met the Berlin definition of ARDS and were admitted to a tertiary care ICU between January 2023 and January 2025. Demographic data, etiologies, comorbidities, arterial blood gas parameters, SOFA scores, ICU stay, and outcomes were analyzed, and p < 0.05 was considered significant.
resultsThe patient population consisted of individuals aged 20-80 years, with a mean age of 54.8 ± 12.3. Notably, 62% were male patients. Community-acquired pneumonia (25%) and sepsis (20%) were leading causes, followed by aspiration pneumonitis (17%). Common comorbidities included hypertension (28%), diabetes (22%), and chronic obstructive pulmonary disease (19%). At admission, patients were classified according to the Berlin Definition into mild, moderate, and severe ARDS based on the partial pressure of oxygen in arterial blood (PaO₂)/fraction of inspired oxygen (FiO₂) ratio. The mean ICU stay was 7.8 ± 4.2 days, and overall mortality was 60%. Significant associations were observed between ARDS severity and clinical outcome (p = 0.001); between SOFA scores at admission and at 48 hours and mortality (p < 0.0001); and between SOFA score and length of ICU stay (p < 0.0001). Mortality increased progressively with increasing ARDS severity and higher SOFA scores.
conclusionsInfection-related ARDS, predominantly due to pneumonia and sepsis, was the major contributor to ICU mortality. Elevated SOFA scores and low PaO₂/FiO₂ ratios were strong predictors of poor outcome. Early recognition and serial organ dysfunction monitoring are essential to improve survival.
