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
backgroundThis study aimed to clarify the development of joint movement patterns during gait in Japanese children aged 3-12 years.
methodsThe participants included 92 children (25 in the 3-4 to year-old group, 28 in the 5-6 to year-old group, 20 in the 7-8 to year-old group, and 19 in the 9-12 to year-old group) and 21 young adults (adult group). Kinematic data during gait were recorded using a three-dimensional motion analysis system and four force plates.
resultsThe patterns of joint motion in the hip joint were similar across all the age groups. The maximum knee joint flexion angle during the swing phase was significantly greater in the 3-4-year-old and 5-6-year-old groups than in the adult group (p < 0.01). The minimum ankle joint angle during the loading response (LR) was significantly greater in the 3-4-year-old and 5-6-year-old groups than in the adult group (p < 0.01). Furthermore, the 7-8-year-old group did not exhibit the pattern observed in adults, where the ankle transitions from plantarflexion to dorsiflexion during the LR phase.
conclusionsAlthough the hip joint showed patterns similar to those of adults at all ages, knee joint motions were greater in 3-8-year-old children than in adults. In regard to ankle joint motion, the heel-rocker function in the LR was suggested to mature after the age of 9 years.
