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

backgroundPaucity of evidence exists as to the prognostic significance of mild to moderate alkalemia upon presentation to the emergency department (ED).

methodsPatients presenting to the ED of one tertiary hospital over the last 24 years were included in this retrospective cohort study if the serum pH drawn within 3 h of the initial presentation was 7.45–7.55. Alkalemia was defined as primarily metabolic (PM) if PCO2≥35mmHg, and primarily respiratory (PR) if HCO3≤24mEq/L - otherwise, the etiology was considered to be mixed and the case was excluded from this analysis. The primary outcome was 30 days mortality, analysed by Cox’s regression.

resultsOf 25,884 patients included in the final analysis, 14,802 (47.4%) were PM and 11,082 (35.4%) PR. Adjusted for age, comorbidities, severity scores, potassium derangements, and year of admission, PR was associated with increased 30-day mortality (aHR 1.21, 95% CI [1.12–1.32]). The association of higher degree of alkalemia with increased mortality was significant only in the PM group (p < 0.001).

conclusionsThe etiology of alkalemia (PR vs. PM) could provide important prognostication in the ED, even in mild to moderate cases.
