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

backgroundRuminants with left-sided abomasal displacement (LDA) often develop metabolic alkalosis and paradoxical aciduria. HYPOTHESIS/

objectivesTo descriptively characterize electrolytes and acid-base variables in cows with LDA compared to healthy cows using the physicochemical (Stewart) approach, and to exploratively assess the influence of blood and urinary electrolytes on pH. ANIMALS: Twenty healthy dairy cows and 20 cows with LDA.

methodsRetrospective cross-sectional study. Electrolytes, pH, total protein (TP), β-hydroxybutyrate (BHB), and glucose were measured in venous blood and urine. Base excess, anion gap, strong ion difference (SID), and strong ion gap (SIG) were calculated. Associations were evaluated using 2 stepwise forward multiple linear regression models.

resultsCows with LDA had significantly lower venous concentrations of sodium, chloride, potassium, magnesium, and calcium (P = .0013, P = .0023, P < .001, P < .001, P < .001), higher BHB (P < .001), and higher blood pH (P = .003) compared to controls. Calculated SID3, SID4, SID5, and SIG did not differ significantly between groups (P = .2, P = .37, P = .40, P = .62). In urine, cows with LDA showed significantly lower concentrations of Na+, K+, Cl-, Mg2+, and HCO₃- (P = .0007, P < .001, P < .001, P = .004, P < .001). Urinary SID3 and SID5 were also significantly lower (both P < .001). CONCLUSIONS AND CLINICAL IMPORTANCE: Acid-base disturbances in cows with LDA can be interpreted using the physicochemical approach. Alterations in electrolyte concentrations contribute to changes in pH.
