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

backgroundShoulder hemiarthroplasty (HA) is a well-established treatment for various humeral-side pathologies. Overstuffing should be avoided because it is associated with glenoid wear; however, specific radiological reconstruction targets remain unclear. This study assessed the association between radiological joint restoration in stemmed and stemless HA and long-term functional outcomes.

methodsPatients who underwent stemmed or stemless HA between 2001 and 2011 were included in a long-term follow-up. Cases with incomplete or non-calibratable digital radiographs or concomitant glenoid procedures were excluded. Clinical outcomes were evaluated using the Constant-Murley Score (CMS) and satisfaction questionnaires. Radiographic parameters-lateral glenohumeral offset (LGHO), lateral humeral offset (LHO), and center of rotation (COR)-were measured on standardized anteroposterior radiographs pre- and postoperatively by two independent observers. Differences from baseline to final follow-up (ΔLHO, ΔLGHO, ΔCOR) were calculated. Interobserver reliability was determined using the intraclass correlation coefficient (ICC). Associations between radiological measures and clinical outcomes were analyzed using linear regression; intergroup comparisons used unpaired t-tests (p < 0.05).

resultsForty-eight patients (12 stemmed, 36 stemless HA) were examined after a mean follow-up of 16.6 ± 2.5 years. CMS did not differ between groups (stemmed 50.5 ± 20.8 vs. stemless 54.1 ± 20.4, p = 0.603). Complete radiographic data were available for 25 patients. Interobserver agreement was excellent for LHO (ICC = 0.93) and very good for LGHO (ICC = 0.85). Mean reconstruction values were close to zero for LHO (ΔLHO = - 0.3 ± 5.1 mm), slightly underreconstructed for LGHO (ΔLGHO = - 6.3 ± 12.9 mm), and slightly medialized for COR (ΔCOR = - 3.5 ± 8.5 mm). Linear regression revealed a significant negative association between ΔLHO and CMS (R² = 0.45; coefficient = - 4.9; p = 0.02).

conclusionBoth stemmed and stemless HA achieve satisfactory long-term outcomes after over 16 years. Accurate reconstruction of the lateral humeral offset correlates with improved functional results.
