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

objectiveTo investigate the associations between clinical, procedural, and radiographic factors and outcomes of steroid hip injections, including long-term and immediate pain reduction, time to arthroplasty, time to reinjection, and the total number of injections. MATERIALS AND

methodsAll intra-articular anesthetic and steroid injections of the hip under fluoroscopic guidance between January 2014 and March 2016 were retrospectively reviewed. Hip radiographs were scored using the Kellgren-Lawrence (KL) and Osteoarthritis Research Society International (OARSI) scores. Immediate pain relief and response were evaluated using a change in visual analog scale and OMERACT-OARSI criteria respectively. Long-term pain relief was evaluated at 2‑7 months after injection by reviewing the medical records. Correlation between patient characteristics, procedural variations, and radiographic factors with injection outcomes was analyzed by using linear and logistic regression models.

resultsOf 361 injections, 79.8% showed an immediate pain response and 32.7% had subjective long-term pain relief (> 2 months). There was no significant correlation between immediate pain relief and response with long-term pain relief and other outcomes. Older age and higher KL score, OARSI-central joint space narrowing (JSN), and inferior acetabular osteophyte were correlated with long-term pain relief (p = 0.01‑0.03). Higher KL and OARSI grades, particularly JSN, were significantly correlated with increased immediate pain relief and total number of injections but decreased time to arthroplasty. Baseline pain positively correlated with immediate pain response (p < 0.001).

conclusionsOlder patients with higher grades of radiographic OA and high baseline pain were good candidates for steroid injections, particularly for those patients awaiting hip arthroplasty.
