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
introductionLoosening of hip implants causes severe pain and disability. Revision surgery, the standard treatment, carries high risks, especially for frail patients. Therefore, a less-invasive treatment option is needed for patients with incapacitating pain. We evaluated the safety and efficacy of percutaneous periprosthetic cement injection (PPCI) to restabilise loosened hip implants.
methodsAll patients treated with PPCIs of hip implants between 2004 and 2020 were retrospectively included (median follow-up 24 months, IQR 11-51). Cement was injected in the periprosthetic space of the loosened hip implant under fluoroscopy. Patient characteristics and the Charlson Comorbidity Index (CCI) were measured. Pain reduction was measured by the Harris Hip pain-subscore and adverse events were recorded.
results34 patients were included (mean age 83 years, median CCI 6 points). 10 patients had a second PPCI after 12 months (median, IQR 7-27). 2 patients needed revision surgery. 30 patients had pain reduction and 4 had no pain reduction. Adverse events included femoral fissure during needle placement (
conclusionsPPCIs for loosened hip implants is feasible in frail patients with pain reduction in the majority of patients and has limited adverse events.
