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 the effectiveness of the Evans lateral lengthening calcaneal osteotomy (E-LLCOT) in treatment of talocalcaneal coalition (TCC) with hindfoot valgus deformity.
methodsBetween January 2014 and October 2017, 10 patients (13 feet) of TCC with hindfoot valgus deformities underwent E-LLCOTs. There were 6 males (8 feet) and 4 females (5 feet) with an age of 13-18 years (mean, 15.8 years). The disease duration was 10-14 months (mean, 11.5 months). The foot deformity was characterized by hindfoot valgus, forefoot abduction, and collapse of the medial arch. Pain site was the tarsal sinus in 4 feet, TCC in 5 feet, and ankle joint in 4 feet. There were tightness of the gastrocnemius in 3 cases (4 feet) and Achilles tendon in 7 cases (9 feet) on Silverskiold test. The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 46.54±9.08 and visual analogue scale (VAS) score was 6.54±0.88 after walking 1 kilometer. The AOFAS ankle-hindfoot score and VAS score were adopted to evaluate the postoperative function of the foot. The talar-first metatarsal angle (T1MT), talonavicular coverage angle (TCA), talar-horizontal angle (TH), calcaneal pitch angle (CP), and heel valgus angle (HV) were measured after operation.
resultsAll incisions healed by first intention. All patients were followed up 12-30 months (mean, 18 months). At last follow-up, the AOFAS ankle-hindfoot score and VAS score were 90.70±6.75 and 1.85±0.90, respectively, showing significant differences when compared with preoperative scores (
conclusionFor TCC with severe hindfoot valgus deformity, E-LLCOT can effectively correct deformity and relieve pain.
