1 · What the graph read from it

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.

2 · The registry

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

purposeThe two year results of a multi-centre clinical trial were examined to evaluate surgical treatment of hallux rigidus using a novel, bi-phasic, biodegradable, and cell-free aragonite-based scaffold (Agili-C™, CartiHeal Ltd, Israel).

methodsTwenty patients with moderate-to-severe hallux rigidus were recruited. After thorough metatarsophalangeal joint (MTPJ-1) debridement, the scaffolds were implanted into the defect centre. Eight patients received concomitant osteotomy. Treatment outcome was followed clinically (Pain VAS, FAAM-ADL, FAAM-Sport, AOFAS-HMIS, maximum active range of extension ROM-EXT, and flexion ROM-FLEX), and by medical imaging, at six month intervals for two years. Adverse events were recorded throughout the study follow-up period.

resultsSignificant clinical improvement over time was observed in all evaluated parameters (screening to final evaluation averages: Pain VAS 59 to 26, FAAM-ADL 57 to 77, FAAM-Sport 39 to 66, AOFAS-HMIS 51 to 81, ROM-EXT 18° to 36°), except for ROM-FLEX. Radiographs showed stable MTPJ-1 width over the two years in 17/18 cases (94%). MRI demonstrated progressive implant biodegradation, coupled with articular cartilage and subchondral bone regeneration, with a repair tissue defect fill of 75-100% in 14/17 (82%) subjects at their final visit. Revision surgery with implant removal was performed in two patients.

conclusionBi-phasic, osteochondral, biodegradable, aragonite-based scaffold demonstrated positive clinical outcome and a good safety profile in the treatment of medium-to-advanced hallux rigidus. According to the medical imaging, this implant has the potential to restore the entire osteochondral unit of metatarsal head.
