The effect of HIV prevalence, CD4 counts and disease severity on the outcome of total knee arthroplasty for haemophilic arthropathy: a systematic review and meta-analysis.
Synthesis in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeEnd-stage knee arthropathy is a recognised complication of haemophilia. It is often treated by total knee arthroplasty (TKA), which is more technically challenging in patients with haemophilia (PwH). It remains unclear what factors may predict implant survivorship and deep infection rate. Therefore, we systematically review the evidence regarding TKA survivorship and infection in PwH, compared to the general population, and determine the important factors influencing survivorship, particularly HIV and CD4 + count.
methodsA systematic literature review was conducted using MEDLINE, EMBASE, and PubMed for studies reporting Kaplan-Meier survivorship for TKA in PwH (PROSPERO CRD42021284644). Meta-analysis was performed for survivorship, and the results compared to < 55-year-olds from the National Joint Registry (NJR). Meta-regression was performed to determine the impact of relevant variables on 10-year survivorship, with a sub-analysis focusing on HIV.
resultsTwenty-one studies were reviewed, totalling 1338 TKAs (average age 39 years). Implant survivorship for PwH at 5, 10, and 15 years was 94%, 86%, and 76% respectively. NJR-reported survivorship for males < 55 years was 94%, 90%, and 86%. Survivorship improved over time (1973-2018), and correlated inversely with HIV prevalence. Infection rate was 5%, compared to 0.5-1% in the NJR. Infection was not significantly increased with higher HIV prevalence, and CD4 + count had no effect. Complications were inconsistently reported.
conclusionSurvivorship was similar at 5 years but declined thereafter, and infection rate was six-fold higher. HIV was related to worse survivorship, but not increased infection. Meta-analysis was limited by inconsistent reporting, and standardised reporting is required in future studies.
