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
backgroundSepsis-associated liver injury (SALI) has a high mortality rate, but there is no established prognostic criterion for its outcomes. Although serum phosphate levels have been associated with mortality in several critical illnesses, research on their relationship with SALI is limited. This research aimed to explore the association between serum phosphate levels and 28-day mortality in SALI patients.
methodsWe enrolled patients with SALI from the Medical Information Mart for Intensive Care-IV database. Serum phosphate levels were recorded within the initial 24 h of Intensive Care Unit admission. The primary outcome of interest was 28-day mortality. Multivariable Cox regression was applied to examine the association between serum phosphate and mortality. Additional subgroup analyses were carried out to ensure these findings.
resultsWe analyzed data from 538 SALI patients, with a mean age of 69 years, of 61.9% male. The 28-day mortality rate was 35.1%. In the unadjusted analysis, higher phosphate levels at admission were significantly linked to increased 28-day mortality (hazard ratio [HR], 1.23; 95% confidence interval [CI], 1.18 to 1.29; p < 0.001). After controlling for covariates such as age, sex, race, laboratory results, comorbidities, and illness severity, the association remained significant (HR, 1.13; 95% CI, 1.04 to1.22; p = 0.006). Subgroup confirmed the consistency of these findings.
conclusionHigher serum phosphate levels at admission were independently linked to increased 28-day mortality in SALI patients. This suggests that serum phosphate could be a useful prognostic marker for risk stratification and clinical management in SALI. CLINICAL TRIAL NUMBER: Not applicable.
