Natural outcome of hemoglobin and functional recovery after the direct anterior versus the posterolateral approach for total hip arthroplasty: a randomized study.

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.
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
backgroundTotal hip arthroplasty (THA) is one of the most successful orthopedic surgeries. There are many common surgical approaches for THA. The direct anterior approach (DAA) and posterolateral approach (PLA) were compared, leading to controversial results.
methodsWe report on a prospective randomized study which compared the changes of perioperative hemoglobin (Hb), the Harris hip score (HHS) and a visual analog scale (VAS) pain score following THA using DAA or PLA. A total of 130 participants were randomly divided into two groups (65 DAA versus 65 PLA). Perioperative ΔHb and other clinical outcomes were recorded.
resultsA total of 130 participants completed follow-up, while 14 patients were not recorded in blood outcomes due to blood transfusions and complications. The average Hb decrease immediately after surgery in the DAA group was greater than that in the PLA group (21.1 versus 15.8 g/L, P < .001). However, post-operative Hb descent velocity was slower in the DAA group, and the lowest point was reached earlier. No significant differences in ΔHb levels could be observed after 1 month in the two groups. When compared with the PLA group, the DAA group had a shorter incision (9.1 versus 13.5 cm, P < .001) and shorter hospital stay (4.2 versus 4.7 days, P = .004). However, the operation time of the DAA group was longer (88.0 versus 66.8 min, P < .001). The DAA group had a better HHS and VAS pain score at 6 weeks post-surgery. However, no significant differences were observed at later time points.
conclusionWe concluded that DAA performed better on enhanced recovery after surgery (ERAS) than PLA in THA, while both DAA and PLA could result in a positive, similar result after 3 months.
trial registrationThe study was registered by the Chinese Clinical Trial Registry (ChiCTR1900020770, 19 January 2019).
