Women recover faster than men after standard knee arthroplasty.
Article in Clinical orthopaedics and related research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00951990 (A Multicenter Randomized Controlled Trail of Ergometer Cycling After Hip and Knee Replacement Surgery), which is not on this map.

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.

Abstract
backgroundSpecific anatomic differences are believed to account for gender-specific function and health-related quality of life after TKA. However, there are conflicting data in the literature regarding these gender-specific outcomes, especially as woman appear to have surgery later in the course of the disease compared with men. QUESTIONS/PURPOSES: We asked whether (1) women had worse knee function and health-related quality of life after TKA compared with men, (2) lower improvements in scores, and (3) slower recovery after surgery.
methodsUsing a cohort study design, we retrospectively analyzed prospectively collected data from three multicenter randomized controlled trials evaluating rehabilitation measures after standard unisex knee arthroplasty in 494 patients (141 men and 353 women). The primary outcome was self-reported physical function as measured by the WOMAC at 3, 6, 12, and 24 months after surgery. Secondary outcomes included the pain and stiffness scales of the WOMAC and the physical and mental component summaries of the SF-36. At the time of surgery, the women were on average older (70.8 versus 67.8 years), had lower mean physical function (55 versus 47), higher mean pain scores (54 versus 48), and greater stiffness (54 versus 46) as measured by the WOMAC.
resultsAt the 3-, 6-, 12-, and 24-month followups, men and women had similar WOMAC scores. Improvements were greater for women compared with men for WOMAC function and pain subscale scores at the 3-month (function, 28 versus 23; pain, 32 versus 25) and 6-month followups (function, 32 versus 27; pain, 36 versus 31). At the 12- and 24-month followups we noted no differences in improvement between men and women.
conclusionAlthough women had greater functional limitations at the time of surgery than men, they recover faster early after standard TKA although function is similar at 12 and 24 months. Women also had greater improvement of WOMAC scores after standard TKA than men. LEVEL OF EVIDENCE: Level II, prognostic study.
