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

purposeThis systematic review and meta-analysis aimed to identify whether posterior tilt increases the risk of treatment failure in nondisplaced femoral neck fractures.

methodsWe searched the databases of the PubMed, Embase, and Cochrane Library from 1980 to 2022. The search strategy was based on the combination of keywords "nondisplaced," "hip fracture," "femoral neck fracture," and "internal fixation." Cohort studies enrolled patients with nondisplaced (Garden I and Garden II) femoral neck fractures were included. Two investigators independently extracted data and the other two assessed the methodological quality. Data were analyzed using Review Manager software.

resultsWe analyzed 13 cohort trials with a pooled sample of 4818 patients, with posterior tilt ≥ 20° in 698 patients and < 20° in 3578 patients in 11 trials, and posterior tilt ≥ 10° in 483 patients and < 10° in 496 patients in 4 trials. All studies were of high quality based on Newcastle-Ottawa Scale evaluation. Treatment failure was reported in 24.4% (170/698) of patients with posterior tilt ≥ 20° and 10.9% (392/3578) of patients with posterior tilt < 20°, indicating that posterior tilt ≥ 20° was significantly associated with a higher risk of treatment failure (Risk ratio, 2.73; 95% confidence interval [CI], 1.77-4.21). Posterior tilt ≥ 10° was not found to be a risk factor for fixation failure (risk ratio, 1.92; 95% CI 0.76-4.83).

conclusionNondisplaced femoral neck fractures with posterior tilt ≥ 20° were associated with an increasing rate of failure when treated with internal fixation. LEVEL OF EVIDENCE : III, Systematic review and meta-analysis.
