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
introductionSecondary fracture prevention is essential to current hip fracture management. However, many patients are discharged without the appropriate anti-osteoporotic medication (AOM). This study aims to evaluate the impact of the implementation of an in-hospital, surgeon-led AOM algorithm on patients with fragility hip fractures. The three outcome events of interest assessed were (a) the AOM initiation (b) the persistence to medication at 2 years of follow-up and (c) the secondary fracture incidence within 2 years of AOM initiation in the treated and control groups. MATERIALS AND
methodsThis was a three-arm controlled before-after quasi-experimental study. A group of hospitalized patients with low-energy hip fractures who were prescribed AOM according to the surgeon-led AO algorithm between March 2020 and May 2022, were compared with a group of concurrent control patients who refused the treatment over the same 2 year period, and a group of historical control patients who were hospitalized for hip fragility fractures in 2 years before the algorithm was introduced (February 2018 to February 2020). AOM initiation rates, 2 year medication persistence, and risks of secondary osteoporotic fracture were assessed and compared between groups.
resultsIn this study, we enrolled 598 patients (mean age 82 ± 8 years, 78% female). Post-fracture AOM initiation increased from 15% (41/281) before to 67% (213/317) after introducing the algorithm. Medication persistence after 2 years of AOM initiation was 56% (95% confidence interval [CI] 49-63%) in treated patients and 52% (95% CI 36-66%) in historical controls. Secondary osteoporotic fractures occurred in 15/213 (7%) treated patients, 8/104 (8%) concurrent control patients, and 20/281 (7%) historical-control patients over an average follow-up of 20.4 months. Multivariable Cox regression analysis did not demonstrate significantly different fracture risks in historical controls (cause-specific hazard ratio [csHR] 0.92; 95%CI 0.45-1.89) or concurrent controls (csHR 1.08; 95% CI 0.45-2.57) compared to treated patients.
conclusionThe AO Foundation algorithm can increase AOM initiation at hospital discharge, retaining high medication persistence 2 years post-fracture. A longer follow-up period is required to evaluate the algorithm's effect on secondary fracture prevention.
