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

purposePrior data has set the precedent that female patients fare somewhat worse than men after spine surgery. We aimed to evaluate the effect of gender on patient-reported outcomes after lumbar spine surgery for degenerative pathologies.

methodsWe identified a consecutive cohort of patients from a prospective registry. Absolute values, as well as change scores for back and leg pain severity (numeric rating scale [NRS]), functional disability (Oswestry disability index [ODI]), and health-related quality of life (HRQOL) as assessed by EQ-5D were compared among male and female patients.

resultsOf the 3279 included patients, 1543 (47%) were female. At baseline, women reported higher NRS for back and leg pain, higher ODI, but equal HRQOL (all p < 0.05). Otherwise, both groups had comparable baseline data. The absolute differences in patient-reported outcomes persisted at the 6-week, 12- and 24-months follow-up, with women now additionally reporting worse HRQOL as assessed by EQ-5D (all p < 0.05). For all outcome measures, change scores were equal among male and female patients, as were the incidences of complications and reoperations (all p > 0.05). Clinical success was achieved in 82% of men and 79% of women (p = 0.34).

conclusionsFemale patients are generally scheduled for surgery with a more advanced disease state. While women seem to report more severe symptoms at long-term follow-up, the degree of improvement is equal among men and women. Female patients may thus fare worse in terms of absolute scores, but enjoy the same benefit from surgery in relative terms. These slides can be retrieved under Electronic Supplementary Material.
