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

The objective of this meta-analysis was to investigate the occurrence and determinants of surgical site infections (SSIs) in individuals following orthopaedic surgical procedures. A systematic exploration of articles concerning factors predisposing individuals to SSIs after orthopaedic surgery was conducted across multiple databases, including PubMed, Embase, Cochrane Library and Web of Science, up to March 20, 2024. The Stata 15.0 software was employed to estimate combined odds ratios (ORs) utilizing either a random-effects model or a fixed-effects model based on the degree of heterogeneity among the included studies. Egger's test was used to assess publication bias. Among the 1248 records retrieved, 45 articles were deemed eligible after screening for studies incorporating multivariate analyses of risk factors associated with SSIs. These comprised four case-control studies and 41 cohort studies, collectively involving 1 572 160 patients, among whom 43 971 cases of SSIs were reported postoperatively. Meta-analysis outcomes indicated significant associations between SSIs and the following factors: low Albumin levels (<35 g/L; OR = 2.29, 95% confidence interval [CI]: 1.45-3.62, p = 0.0001), ASA score >2 (OR = 2.32, 95% CI: 1.86-2.89, p = 0.0001), elevated body mass index (BMI) (>24 kg/m
