Serum lactate to albumin ratio at hospital arrival and neurological outcome of out-of-hospital cardiac arrest: a nationwide 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
objectiveWe investigated the possible association between lower serum lactate to albumin ratio upon hospital arrival and out-of-hospital cardiac arrest (OHCA) outcome.
methodsRecords from the Japanese Association for Acute Medicine-Out-of-Hospital Cardiac Arrest (JAAM-OHCA) Registry were used for this multicenter observational study. Enrolled patients were ≥18 years old with OHCA of medical etiology who were hospitalized after spontaneous circulation returned between June 1, 2014, and December 31, 2021. We excluded those with missing data or those who failed to meet predefined inclusion criteria. The primary outcome was a cerebral performance category scale of 1 or 2 which indicated 30-day survival with favorable neurological outcome. Patients were divided into quartiles based on serum lactate to albumin ratios. The multivariable logistic regression analysis included adjustment for multiple factors.
resultsData from 4,413 patients were analyzed. The primary outcome was achieved by 558 of 1,104 patients (50.5%) in the first quartile (lactate to albumin ratio, ≤2.23), 240 of 1,111 patients (21.6%) in the second quartile (lactate to albumin ratio >2.23-3.39), 96 of 1,096 patients (8.8%) in the third quartile (lactate to albumin ratio >3.39-4.70), and 24 of 1,102 patients (2.2%) in the fourth quartile (lactate to albumin ratio, >4.70). Adjusted odds ratios (95% confidence intervals) for the primary outcome in the second, third, and fourth quartile compared with the first quartile were 0.33 (0.26-0.42), 0.19 (0.14-0.26), and 0.07 (0.04-0.11), respectively.
conclusionA statistically significant association between categorization in the lower lactate to albumin ratio quartile group and favorable neurological outcome after OHCA was identified.
