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

unlabelledWe investigated the effects of socio-demographic and health factors on timing and location of hip fracture among 484 subjects. Time of fracture varied between community dwellers and residential care facility dwellers, and in relation to subjects' psychotropic drug status. Indoor hip fracture incidence increased on snow-covered days.

introductionThis paper aims to describe the timing and whereabouts of hip fracture cases in a population-based setting and to relate these factors with residential and health status, seasonal variation, and snow-covered ground.

methodsWe consecutively included 484 incident hip fracture events (age ≥50 years) admitted to a Swedish orthopedic department during a 1-year period. Data concerning socio-demographic details, fall location, time of fracture, comorbidity, and medications were collected from in-patient medical records and through patient or caregiver interviews.

resultsThe expected peak in fracture occurrence during daytime was observed among community dwellers but not among subjects living in residential care. Hip fracture was twice as likely to occur during nighttime hours among psychotropic drug users (adjusted odds ratio (Adj. OR), 2.20; 95% confidence interval (CI), 1.12-4.30) compared to those not receiving these medications. Subjects without dementia, taking psychotropic drugs, were also more likely to fracture during nighttime hours (Adj. OR, 2.91; 95% CI, 1.40-6.0). We observed an increase in indoor hip fracture incidence on snow-covered days among community dwellers (incidence rate ratio, 1.34; 95% CI, 1.02-1.74). We observed only a weak seasonal trend in hip fracture incidence, based on month, among community dwellers who fractured indoors.

conclusionsSpecial attention and possibly fall-preventive efforts should be directed not only toward those living in residential care facilities but also toward community-dwelling subjects taking psychotropic drugs since these groups have a higher incidence of nighttime hip fracture. Further research aiming to explain the seasonal variation of indoor fracture incidence among community dwellers is warranted.
