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
backgroundHallux valgus (HV) is a widespread condition that leads to discomfort in daily life. There are different surgical techniques for HV. This retrospective and comparative study aimed to compare the clinical and radiographic outcomes of the Reverdin-Isham osteotomy (RIO) and the Minimally Invasive Intramedullary Nail Device (MIIND) surgical techniques.
methodsOne hundred ninety-six patients with mild-to-severe HV were enrolled and divided into two groups: 98 patients with mild-moderate HV and 98 with moderate-severe HV, treated with the RIO and MIIND techniques, respectively. Radiographic and clinical evaluations were assessed preoperatively at 3, 12 and 60 months after surgery. Radiologically, the Hallux Valgus Angle (HVA), Intermetatarsal Angle (IMA), Distal Metatarsal Articular Angle (DMAA) and Tibial Sesamoid Position (TSP) were evaluated. Clinically, the AOFAS hallux metatarsophalangeal-interphalangeal scale and the Numeric Rating Scale (NRS-11) for pain were assessed. A propensity score matching (PSM) model was implemented to compare the two techniques.
resultsIn the RIO group, the mean HVA correction from preoperative value to 60 months of follow-up was 8.69° (p < 0.0001), the mean IMA correction was 2.42° (p < 0.0001), and the mean DMAA correction was 0.09°. In the MIIND group, the mean HVA correction was 24.92° (p < 0.0001), the mean IMA correction was 8.75° (p < 0.0001), and the mean DMAA correction was 6.28° (p < 0.0001). The mean AOFAS score improved over time, and NRS-11 decreased in both groups. After PSM model application, the variables that impacted the allocation to RIO or MIIND techniques were age, preoperative HVA values and HV severity.
conclusionOur study demonstrates the efficacy of RIO for mild-moderate HV and MIIND for moderate-severe HV. Radiographic and clinical outcomes improved in both groups, but older patients with higher HVA and severe HV should be treated with the MIIND technique to achieve satisfactory outcomes. LEVEL OF EVIDENCE: III, retrospective cohort study.
