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

purposeWe sought to estimate the prevalence, incidence, and timing of surgery for elective and non-elective hernia repairs.

methodsWe performed a retrospective cohort study, abstracting data on children < 18 years from the 2005-2014 DoD Military Health System Data Repository, which includes > 3 million dependents of U.S. Armed Services members. Our primary outcome was initial hernia repair (inguinal, umbilical, ventral, or femoral), stratified by elective versus non-elective repair and by age. We calculated prevalence, incidence rate, and time from diagnosis to repair.

results19,398 children underwent hernia repair (12,220 inguinal, 5761 umbilical, 1373 ventral, 44 femoral). Prevalence of non-elective repairs ranged from 6% (umbilical) to 22% (ventral). Incidence rates of elective repairs ranged from 0.03 [95% CI: 0.02-0.04] (femoral) to 8.92 [95% CI: 8.76-9.09] (inguinal) per 10,000 person-years, while incidence rates of non-elective repairs ranged from 0.005 [95% CI: 0.002-0.01] (femoral) to 0.68 [95% CI: 0.64-0.73] (inguinal) per 10,000 person-years. Inguinal (median = 20, interquartile range [IQR] = 0-46 days), ventral (median = 23, IQR = 5-62 days), and femoral hernias (median = 0, IQR = 0-12 days) were repaired more promptly and with less variation than umbilical hernias (median = 66, IQR = 23-422 days).

conclusionsThese data describe the burden of hernia repair in the U.S. The large variation in time between diagnosis and repair by hernia type identifies an important area of research to understand mechanisms underlying such heterogeneity and determine the ideal timing for repair. LEVEL OF EVIDENCE: Prognosis study II.
