Relationship between hand grip and pinch strength, body composition, pain threshold, and anxiety in dentists.
Trial report in Irish journal of medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06721117 (Investigation of Grip Strength, Pain and Anxiety Levels in Dentists), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundWork-related musculoskeletal disorders are commonly observed across various occupational groups.
aimThe aim of this study was to evaluate the relationships between hand grip and pinch strength, body composition, pain threshold, and anxiety levels in dentists.
methodsThe study included 49 dentists working at Sakarya Oral and Dental Health Hospital. Participants' grip strength, including pinch and gross grip, was assessed using the Jamar hand dynamometer, while the muscle strength of the forearm flexor and extensor muscles was measured with a handheld dynamometer. Anxiety levels were evaluated using the Beck Anxiety Inventory, and pain threshold was assessed using an algometer.
resultsA positive and significant correlation was found between body mass index (BMI) and dominant and non-dominant hand grip strength (r = 0.485, p = 0.003; r = 0.501, p = 0.002). BMI also showed a strong relationship with dominant and non-dominant finger strength (r = 0.511, p < 0.001; r = 0.557, p < 0.001). A negative correlation was found between Beck Anxiety Score and physical strength parameters, especially non-dominant hand grip strength (r = 0.619, p = 0.005) and dominant hand grip strength (r = - 0.512, p = 0.025) and anxiety levels. Significant positive correlations were found between pain threshold and physical strength parameters, especially non-dominant wrist extensor strength (r = 0.283, p = 0.049) and dominant hand grip strength (r = 0.408, p = 0.015) which were found to increase pain threshold.
conclusionsPhysical and psychological factors have an impact on occupational performance, especially in occupations that require prolonged use of the hands and wrists, such as dentistry.
