Blood and Peritoneal Lactate, Ratio and Difference, and Peritoneal Lactate to Total Solids Ratio for Detection of Intestinal Strangulating Obstructions in Horses.

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
backgroundThe effectiveness of the peritoneal fluid L-lactate-to-total solids ratio (PFL:PFTS) as a diagnostic marker for strangulating lesions of the small intestine (SI) and large colon (LC) has not been investigated.
objectivesDescribe and compare the PFL:PTFS and blood lactate (BL), peritoneal fluid lactate (PFL) and PFL:BL difference and PFL:BL ratio of horses with SI and LC strangulating (SO) and non-strangulating (NSO) obstructions and determine sensitivity and specificity to predict SO. ANIMALS: A total of 282 horses, 117 with SI lesions (59 classified as SINSO and 58 as SISO), and 165 with LC lesions, 126 categorized as LCNSO and 39 as LCSO.
methodsRetrospective study. Receiver operating characteristic (ROC) curves were generated to identify optimal cut-off points to maximize sensitivity and specificity to predict SO.
resultsA PFL:PFTS ratio of 2.9 had fair (area under the curve [AUC], 0.76; 95% confidence interval [CI], 0.67-0.84) ability to discriminate between SISO and SINSO, with sensitivity of 66.7% and specificity of 78.3% to predict SISO. A PFL: PFTS ratio of 3.6 had good ability to discriminate between LCSO and LCNSO (AUC, 0.84; 95% CI, 0.78-0.90) with sensitivity and specificity of 78% and 81% to predict LCSO, respectively. Peritoneal fluid lactate, PFL:BL difference, and PFL:BL ratio also had a low to moderate sensitivity to predict ischemic strangulating lesions of the SI and LC. CONCLUSION AND CLINICAL IMPORTANCE: Strangulating obstructions are critical conditions requiring prompt intervention. The low to moderate sensitivity identified suggests that PFL, PFL:BL difference and ratio, and PFL:PFTS ratio should be interpreted with clinical signs and the response to initial treatment to determine SO accurately.
