Short- and Midterm Comparison of Platelet-Rich Plasma with Hyaluronic Acid versus Leucocyte and Platelet-Rich Plasma on Pain and Function to Treat Hip Osteoarthritis. A Retrospective 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
Hip osteoarthritis (HOA) leads to pain and reduced function. The use of intra-articular injections based on corticosteroids, platelet-rich plasma (PRP), or hyaluronic acid (HA) is becoming a common symptomatic therapy for HOA. For the first time, we compare the effectiveness of plasma with a high concentration of platelets and leukocytes (L-PRP) with PRP+HA in patients with mild to moderate HOA. A total of 26 patients in each group were administered with either L-PRP or PRP+HA. Outcomes were evaluated at baseline, 3 months, and 1 year after the injection. The mean visual analog scale (VAS) and Harris hip score (HHS) within and between groups among different time points were compared using repeated measures ANCOVA (age set as a covariate). Both treatments were effective in reducing VAS, but not in significantly increasing HHS. In the group treated with L-PRP, VAS showed interaction between time and treatment (in favor of L-PRP). Pairwise comparison for treatment and time point evidenced a significant difference at 1-year follow-up between L-PRP and PRP-HA. Outcomes support the idea that both treatments may be effective in reducing pain, with maximal pain reduction achieved after 3 months. L-PRP showed better results in reducing VAS over time. Both treatments are effective at reducing pain in the short to medium term. L-PRP could be the treatment of choice due to a more marked effect over time. Nevertheless, further research is needed to better describe the clinical outcome of these formulations.
