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

purposeRevision total hip arthroplasty (rTHA) is an increasingly common procedure due to the growing number of primary total hip arthroplasties (THAs) performed worldwide. This study evaluates the long-term implant survival, functional outcomes, and radiographic performance of cemented femoral stem (Beznoska s.r.o., Kladno, Czechia) in rTHA.

methodsA retrospective analysis was conducted on 183 patients who underwent rTHA with cemented stem between March 2012 and December 2023. The mean follow-up duration was 71.26(± 39.31) months. Implant survival was analyzed using Kaplan-Meier survival estimates, and failure modes were assessed. Radiographic changes were classified using the Gruen Zones system. Functional outcomes were evaluated using the Harris Hip Score (HHS). Cox proportional hazard models were applied to identify prognostic factors influencing implant survival.

resultsThe five-year implant survival rate was 98.1%, declining to 83.9% at twelve years. The overall failure rate was 3.83%, with periprosthetic infection (4 cases) being the most common cause, followed by aseptic loosening (2 cases). Radiographic changes were observed in 24.03% of cases, predominantly in Gruen Zones 2, 6, and 1. Functional outcomes were favorable, with a mean HHS of 81.28(± 5.74), comparable to outcomes reported for uncemented revision stems. Age, stem diameter, and stem length did not significantly impact implant survival.

conclusionThe cemented stem demonstrated favourable long-term survival, with high implant retention rates. Functional outcomes indicated overall satisfactory performance. Radiographic evaluation revealed localized changes around the implant, predominantly in Gruen Zones 2, 6, and 1. Implant failure was relatively rare, with periprosthetic infection being the most common cause.
