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

objectivesTo evaluate whether clinical characteristics and outcomes of patients with Enterococcus faecalis bloodstream infection (EF-BSI) differ by biological sex.

methodsQuasi-experimental study conducted at two hospitals, comprising a retrospective phase (2017-2019) and a prospective intervention phase (2022-2024), including adults with a first episode of monomicrobial EF-BSI. Patients who died within 72 h or were receiving palliative care were excluded. A structured management bundle was implemented in the intervention phase. Clinical features, bundle adherence, and 90-day mortality were compared by sex. Cox regression was used to assess the association between sex and 90-day mortality.

resultsAmong 250 patients, 77 (31%) were females and 173 (69%) males. Females were younger than males (median 63 [50-76] vs. 73 [63-80] years; p < 0.001). Cardiovascular disease was more frequent in males (30 [39%] vs. 94 [54%]; p = 0.025), whereas immunosuppressive therapy (29 [38%] vs. 35 [20%]; p = 0.004) and connective tissue disease (9 [12%] vs. 2 [1%]; p < 0.001) were more frequent in females. Persistent bacteraemia (2/57 [4%] vs. 30/139 [22%]; p = 0.002) and infective endocarditis (14 [18%] vs. 59 [34%]; p = 0.011) were more frequent in males. Females received fewer bundle measures (5 [3-6] vs. 5 [4-6]; p = 0.028), largely because echocardiography and colonoscopy were less frequently indicated. Ninety-day mortality was 22% (17) in females and 14% (25) in males (p = 0.136). Female sex was associated with higher 90-day mortality after adjustment (aHR 2.00, 95%CI 1.04-3.83).

conclusionsFurther studies should explore the underlying causes of these differences and potential implications for individualized management.
