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
purposeThis study aimed to assess the long-term results of THA patients who received a cementless short stem regarding clinical outcomes, bone changes, complications, and incidence of femoral revision.
methodsA retrospective evaluation of the first 100 THA employing a type 2B cementless stem (Mini hip stem, Corin, Cirencester, United Kingdom) by the same surgeon at one institution. We only include patients with 18 years or more, and with a minimum follow up of 8 years. Patient's Harris hip score (HHS), the University of California, Los Angeles activity score (UCLA), and radiographic outcomes were evaluated.
resultsA total of 100 primary hip arthroplasties with Mini Hip stems were performed on 84 patients, with an average age of 47 years old. The median follow-up was 120 months (IQR 57.5-136.5), with 47 patients having a minimum 10-year follow-up. The patient's HHS improved significantly (p < 0.001) and UCLA's score was 7 (SD 1.7) at the final follow-up. Only one patient suffered an intraoperative lateral cortical perforation, which was treated on the same day with revision of the short stem to a conventional metaphysodiaphyseal fixation stem. Three incomplete fractures of the calcar occurred intraoperative, of which only one required wire cerclage and unloading partial during the 30 days after surgery. No osteolysis, radiolucency, thigh pain, periprosthetic or ceramic fractures were observed. Only 6% hips experience squeaking without the need for revision. Two acetabular components were revised early, but no stem failures were recorded, yielding an incidence density rate of 0% (95% CI 0-0.05%) over 10 years.
conclusionThis study showed that the MiniHip short stem is a reliable option for THA in younger patients, with a high implant survival rate and excellent functional outcomes over the long term.
