Fluid distribution in ankle and midfoot joints: MR findings in asymptomatic volunteers.

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
purposeThe purpose of this study is to assess the amount of fluid in the joints of the ankle and midfoot on MR imaging in asymptomatic volunteers. MATERIALS AND
methodsTwenty-one healthy asymptomatic volunteers (42 ankles) were evaluated with MRI imaging. There were 13 men and 8 women. The mean age was 24.7 years (19-42 years). MR imaging was performed on a 3T MR system using proton density weighted images with fat saturation (TR 2969, TE 30 ms, NA 2, slice thickness 2.5 mm). Images were obtained in three orthogonal planes. The images were interpreted by two radiologists in two sessions. The maximum size of the joint effusion was measured in one plane. Descriptive statistics and variation between interpretation sessions were calculated.
resultsFluid in the anterior tibiotalar joint had a mean size of 2.0 mm (0.0-5.5 mm), in the posterior tibiotalar joint 3.1 mm (0.0-6.3 mm), in the talonavicular joint 0.7 mm (0.0-2.9 mm), and in the anterolateral recess 2.0 mm (0.0-4.3 mm). Fluid in the posterior aspect of the posterior subtalar joint had a mean size of 2.6 mm (0.0-9.4 mm), in the anterior aspect of the posterior subtalar joint 1.9 mm (0.0-6.6 mm), at the middle subtalar joint 0.1 mm (0.0-1.7 mm), and at the anterior subtalar joint 1.6 mm (0.0-6.0 mm). Fluid in the tibiofibular joint had a mean height of 8.1 mm (0.0-16.4 mm).
conclusionIn asymptomatic volunteers, moderate to large amounts of fluid were common in all joint recesses of ankle and midfoot, and most pronounced in the anterior and posterior tibiotalar joint, anterolateral recess, and posterior subtalar joint. This should not be mistaken for evidence of a pathological condition.
