Reliability of the weight-bearing ankle dorsiflexion range of motion measurement using a smartphone goniometer application.
Article in PeerJ, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06080334 (Effectiveness of Dry Needling of the Gastrocnemius Muscle vs. Electrolysis in Subjects With Achilles Tendinopathy), which is not on this map. Cited by 5 papers.
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

Abstract
backgroundWeight-bearing ankle dorsiflexion range of motion measurement (weight-bearing lunge test) is gaining in popularity because it mimics lower extremity function in daily physical activities. The purpose of the study is to assess the intra-rater and the inter-rater reliability of the weight-bearing ankle dorsiflexion range of motion measurement with a flexed knee using a smartphone application Spirit Level Plus installed on an Android smartphone.
methodsThirty-two young, healthy subjects participated in the study and were measured in four sessions by two examiners. One measurement was taken on each ankle in every session. Eight measurements were taken from each participant. A total of 256 were taken from all the participants. The measurements for the individual subject were repeated no sooner than 24 hours after the first session. In order to assess the reliability, intraclass correlation coefficients (ICC), standard error measurements (SEM) and minimal detectable change (MDC) at the 95% confidence interval were calculated.
resultsStatistical data analysis revealed moderate intra-rater reliability for the right ankle (ICC = 0.72, 95% CI [0.49-0.85]) and good intra-rater reliability for the left ankle (ICC = 0.82, 95% CI [0.66-0.91]). Inter-rater reliability is moderate for the right (ICC = 0.73, 95% CI [0.52-0.86]) and the left ankle (ICC = 0.65, 95% CI [0.39-0.81]).
conclusionThe observed method is moderately reliable and appropriate when the main objective is to assess ankle dorsiflexion mobility in weight-bearing when weight-bearing is not contraindicated. The concurrent validity of the Spirit Level Plus application is excellent.
