Predicting the outcome of asymptomatic univesicular liver hydatids: diagnostic accuracy of unenhanced CT.
Article in European radiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesTo establish the role of unenhanced CT in predicting the outcome of liver hydatid cysts. We sought to determine whether the presence of laminated membrane detachment (LMD) or pericyst degenerative changes (PDCs) detected on CT were reliable signs for predicting a favorable outcome of liver hydatids.
methodsIn a 20-year-long study, we prospectively followed changes occurred in CT of 106 cysts of 98 patients with incidentally discovered asymptomatic univesicular liver hydatids who accepted to enter a watch-and-wait program. An "unfavorable" outcome was defined as the occurrence of a complication (most commonly, cyst fistula or infection) or increase in the cyst size during the follow-up; otherwise, the outcome was considered "favorable." The parameters derived from a binary logistic regression analysis (with the outcome taken as the dependent variable), after appropriate transformation of the independent variables (presence of LMD or PDCs on CT), were used to calculate the sensitivity, specificity, positive and negative likelihood ratios, and positive and negative predictive values of the presence of either the abovementioned CT findings for the prediction of a favorable outcome.
resultsThe presence of LMD or PDCs had a high specificity (88%) and positive predictive value (96%) for a favorable outcome; they had high false-negative rates.
conclusionsThe presence of either LMD or PDCs on unenhanced CT, in incidentally discovered asymptomatic univesicular liver hydatids, was associated with a high probability of a favorable outcome. Their absence does not rule out a favorable outcome. KEY POINTS: • Computed tomography can be used for predicting the outcome of those with incidentally discovered univesicular liver hydatids. • The presence of laminated membrane detachment and/or pericyst degenerative changes is associated with a favorable outcome. • Their absence does not necessarily indicate an unfavorable outcome.
