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
purposeThe conjoined tendon-preserving posterior (CPP) approach is a modified posterior approach for total hip arthroplasty (THA) that preserves the short external rotator muscles and most ischiofemoral ligaments. The objective of the present study was to compare the short-term clinical outcomes, complications, and imaging evaluations of CPP and posterior approaches in THA.
methodsThis retrospective study included 83 patients from May 2018 to September 2021: 36 patients with 42 hips who underwent THA with the CPP approach (CPP group) and 47 patients with 60 hips who underwent THA with the standard posterior approach (PA group) with a minimum of 2 years of follow-up. Assessment tools included operative times, blood loss, preoperative and last follow-up Harris Hip Scores (HHS), postoperative complications, and implant placement angles between the groups. Statistical analysis was performed using chi-square tests and T-tests.
resultsThe CPP approach had a significantly longer operative time and greater blood loss compared to the PA group. Preoperative and postoperative HHS were not significantly different between groups. Considering complications, the PA group had one case each of dislocation and infection, and the CPP group had two cases of sciatic nerve palsy, but the difference was not significant. Cup anteversion, inclination and stem anteversion were not significantly different between groups.
conclusionFunctional outcomes, complication rates, and implant placement angles were comparable with the posterior approach, and the CPP approach has the potential to reduce postoperative dislocations. However, careful attention should be paid to sciatic nerve palsy during early initiation of the CPP approach, and this study did not demonstrate that the CPP approach was clearly superior to the posterior approach.
