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

backgroundMany studies report differences in patient-reported outcome measures (PROMs) for men and women undergoing total hip arthroplasty (THA). Few studies have evaluated whether these are explained by corresponding differences in important preoperative factors. QUESTIONS/PURPOSES: (1) Are there differences between men and women in PROM scores preoperatively and 12 months after THA? (2) Do baseline differences in comorbidity, age, body mass index (BMI), and mental health status explain these differences in PROM scores?

methodsPreoperatively, 300 patients completed the Oxford Hip Score (OHS), WOMAC, and SF-12; 261 (86%) of them (129 women, 64 ± 11 years; 132 men, 66 ± 10 years) completed the same questionnaires 12 months postoperatively and also rated the acceptability of their current symptoms and change in general health.

resultsPreoperatively, women showed worse scores than men in the OHS (-1.9; 95% confidence interval, -3.6 to -0.3) and WOMAC (-6.3; -10.9 to -1.7). At 12 months postoperatively, the absolute scores for all PROMs were not significantly different. After controlling for BMI, age, comorbidity, SF-12 mental health scores, and sociodemographic characteristics, the baseline differences remained.

conclusionsSurgeons may be more reluctant to operate on women than men because they perceive that, because of their worse baseline status, women are likely to have worse outcomes; however, given that we found no evidence for differences in patient-reported outcomes at 12 months, these suspicions would appear to be unfounded. Women and men can be expected to benefit to a similar extent from THA. LEVEL OF EVIDENCE: Level III, therapeutic study.
