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
BACKGROUND/
objectivesThis preliminary pilot case series aims to evaluate the feasibility and temporal evolution of pain and function following an ultrasound-guided infiltration technique with hyaluronic acid and methylprednisolone in a specific patient population with Temporomandibular Disorders (TMD) characterized by MRI-confirmed retrodiscal tissue hyperemia. Given the absence of a control group, this study represents a preliminary exploration of a clinical approach utilizing individualized interocclusal devices during infiltration.
methodsTwenty-eight patients (16 females, 12 males) with TMD and MRI evidence of retrodiscal tissue hyperemia were enrolled in this prospective, uncontrolled study. A unique protocol was employed, utilizing individualized interocclusal devices to optimize joint space access during bilateral ultrasound-guided infiltration of a mixture containing low-molecular-weight hyaluronic acid, lidocaine, and methylprednisolone acetate. Pain intensity (VAS 0-100 mm) and associated symptoms (tinnitus, vertigo, headache, joint clicking) were assessed at baseline and at 30, 60, and 90 days' follow-up.
resultsA statistically significant temporal reduction in pain was observed at all follow-up points (
conclusionsThe ultrasound-guided infiltration technique, combined with personalized interocclusal support, demonstrated preliminary feasibility and short-term temporal improvement in pain and joint clicking in this specific patient cohort. Due to the lack of a control group and the multimodal nature of the intervention, these findings should be considered preliminary and do not allow for causal inferences regarding the efficacy of individual components.
