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
objectiveTo investigate whether ultrasound greyscale (GS) and power Doppler (PD) joint inflammation may be useful in identifying rheumatoid arthritis (RA) patients in different states of structural damage and disease activity.
methodsIn this cross-sectional study utilizing 36-joint ultrasonography, bone erosion was scored dichotomously (1 = yes/0 = no) while GS and PD joint inflammations were graded semi-quantitatively (0-3) at each joint recess. Sensitivity, specificity and receiver operating characteristic (ROC) curve analysis was applied to study ultrasound joint inflammation as a clinical marker for identifying patients with erosion score > 4.5 (median) and DAS28 > 2.6, > 3.2 and > 5.1, respectively.
results1080 joints and 1800 joint recesses were scanned in 30 RA patients (mean disease duration, 70.3 months). Patients with GS score > 35.5 (median) had significantly higher ultrasound erosion scores when compared to those with GS score ≤ 35.5 (mean (95% CI) ultrasound erosion scores, 9.27 (6.12-12.4) versus 3.33 (2.31-4.36), respectively. p = 0.0027). Patients with PD positivity had significantly higher DAS28 scores compared to those with PD negativity (mean (95% CI) DAS28, 3.84 (3.35, 4.34) versus 2.86 (2.18, 3.54), respectively. p = 0.0457). Area under the ROC curve (AUC) based on cut-off GS scores ≥ 38 to identify patients with ultrasound erosion score >4.5 was 0.82 (sensitivity = 73.3%, specificity = 86.7%, accuracy = 80%). AUC based on cut-off PD scores ≥ 2.5 for identifying patients with DAS28 > 5.1 was 0.88 (sensitivity = 100%, specificity = 69.2%, accuracy = 73.3%).
conclusionsUltrasound GS and PD joint inflammation scores can be useful in identifying RA patients with high bone erosion burden (ultrasound erosion score > 4.5) and high disease activity (DAS28 > 5.1), respectively.
