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
purposeThe UniCAP (®) implant for femoral resurfacing treatment of large cartilage lesions and early OA was introduced in 2006. The outcome of the present study is from a prospective cohort study of 64 patients, followed 2 years clinically and 7 years for revisions.
methodsFrom 2009 to 2013, 64 patients were treated with femoral resurfacing using the UniCAP implant. Indication for treatment with UniCAP implant was symptomatic huge cartilage lesion or early OA at the femoral condyle demonstrated by MRI or arthroscopy, which was ICRS grades 3-4 and more than 4 cm(2). There were 28 males and 36 females with a median age of 51 (range 35-65) years. Patients were followed for 2 years clinically with Knee Society subjective outcome scores (KSS), pain scores and radiographic evaluations and for 7 years with complications and reoperations.
resultsAt 2 years, the follow-up mean KSS improved from 49 (6.9) to 88 (17.1), the mean KSS function score improved from 46 (8.0) to 90 (17.1), and the mean Pain score improved from 7.4 (0.5) to 2.3 (1.4). 47 % of the implants were revised within 7 years to arthroplasty due to the progression of cartilage lesions, progressing of osteoarthritis or increased knee pain. The reoperation rate did not show any significant difference between females and males. The Kaplan-Meier survival rate was 50 % at 7 years, no difference among females and males.
conclusionThe present study demonstrated an improved subjective outcome and reduced pain after femoral resurfacing using the UniCAP (®) implant in a relatively large cohort of patients with symptomatic large cartilage lesions or early OA. A 47 % reoperation rate with conversion to arthroplasty was found. The femoral resurfacing implantation can be a temporary treatment for large cartilage lesions or early OA that is expected to develop into osteoarthritis. For younger patients who are ineligible for arthroplasty treatment, this implant can offer a temporary solution. LEVEL OF EVIDENCE: IV.
