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

purposeThis study evaluates the survivorship and clinical outcomes of revision total hip arthroplasty (THA) to treat symptomatic leg length discrepancy (LLD) via limb shortening.

methodsA total of ten patients were included who underwent revision THA to treat LLD via limb shortening at a single arthroplasty center from January 1, 2000, to December 31, 2022, representing 0.4% (ten of 2763) of all revision THA during this period. Among these cases, six of ten (60.0%) were men, mean age at index surgery was 62 years (range, 39 to 81), and mean follow-up was 7.63 years (range, 3.51 to 15.73). Kaplan-Meier survivorship analysis was conducted with failure defined as revision surgery for any reason.

resultsKaplan-Meier survivorship for failure due to any cause was 100.0% at five years, with nine hips at risk and 80.0% at ten and 15 years with one hip at risk. One patient failed due to dislocation. The mean LLD significantly improved from a pre-operative value of 24.5 mm (SD 7.25) to a post-operative value of 1.25 mm (SD 3.17) (P < 0.001). There was a significant increase in Harris hip scores from 50.44 (SD 11.11) pre-operatively to 75.4 (SD 19.35) at one year (P = 0.0172) and 84.6 (SD 12.44) at three years post-operatively (P = 0.011).

conclusionRevision total hip arthroplasty to treat LLD via limb shortening provides favourable 5- to 10-year survivorship and clinical outcomes.
