Ruling out deep vein thrombosis in patients with superficial vein thrombosis: external validation of the ICARO score.
Article in Journal of thrombosis and thrombolysis, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
A clinical score was recently proposed to rule out concomitant DVT in patients with a clinical suspicion of SVT. This study aimed to assess the external validity of this score in patients from the STEPH study. We performed a post-hoc analysis of data from the STEPH study. The STEPH study was a prospective multicenter community-based study conducted during a 1-year period in the resident adult population of the Greater Saint-Etienne urban area (France). Every patient with a clinical suspicion of SVT underwent a venous compression ultrasonography, to confirm SVT and to assess the presence of a concomitant DVT or not. Odds ratios for concomitant DVT were calculated for each item of the ICARO score. We then computed the score for each patient, and performed a receiver operating characteristic (ROC) curve analysis. In univariate analysis, none of the ICARO items were significantly different given the presence of a concomitant DVT. Given computed scores, 55 patients (45.1%) had a low risk, 17 (13.9%) had an intermediate risk and 50 (41.0%) had a high risk of a concomitant DVT. The area under the ROC curve was 0.386 [95% CI, 0.268-0.504]. When risk levels were dichotomized as low vs intermediate-high risk, the ICARO score had a sensitivity of 36.0%, a specificity of 40.2%, a positive predictive value of 13.4% and a negative predictive value of 70.9%. Our study does not confirm the utility of the ICARO clinical score to rule out concomitant DVT in case of SVT.
