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

backgroundThere is no consensus on the antibiotic course or type of surgical treatment in streptococcal periprosthetic-joint infections (PJIs). We aimed to compare the treatment failure rate at 2 years of PJIs caused by streptococci to PJIs caused by other pathogens and identify factors associated with failure.

methodsIt was a single-center retrospective cohort study conducted between 2009 and 2019. We included all patients aged ≥ 18 years undergoing treatment for hip or knee PJI with a 2-year follow-up. We analyzed the treatment failure rate at 2 years of streptococcal PJIs versus PJIs caused by other pathogens with failure defined as a non-successful treatment using the Delphi-based international multidisciplinary consensus of success. We also analyzed factors associated with failure including streptococcal etiology and type of treatment.

resultsWe included 404 patients; 62 (15%) had a streptococcal PJI, of which 14 (23%) exhibited treatment failure at 2 years. The treatment failure rate was similar to that for PJIs caused by other pathogens (21%, 71/342) (P = 0.78). Streptococci were not associated with failure (OR = 1.55, 95% CI 0.62-3.89, P = 0.35). However, Streptococcus dysgalactiae (OR = 9.45, 95% CI 1.37-65.46, P = 0.02) and debridement, antibiotics and implant retention (DAIR) (OR = 9.31, 95% CI 1.80-48.20, P = 0.008) were associated with failure among patients with a streptococcal PJI.

conclusionsThe treatment failure rate of streptococcal PJIs was similar to that for PJIs caused by other pathogens. However, Streptococcus dysgalactiae and DAIR were factors associated with failure among patients with a streptococcal PJI. Our results suggest that streptococcal PJIs, especially Streptococcus dysgalactiae PJIs, should be surgically treated more aggressively with an implant exchange.
