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
introductionThe optimal surgical treatment approach for calcaneal fractures remains controversial. This retrospective comparative study aimed to compare the clinical and radiological outcomes of minimally invasive locking plate fixation with those of screw fixation for displaced intra-articular calcaneus fractures (DIACFs) treated via the sinus tarsi approach (STA).
methodsA total of 38 patients and 40 feet with DIACFs from 2015 to 2020 were retrospectively reviewed with a minimum of 3 years of follow-up. Patients were divided into two groups based on fixation method: minimally invasive locking plate fixation (MIP group) versus screw fixation (SW group) (17 vs 23, respectively). The clinical outcomes were evaluated by the Visual Analogue Scale (VAS), Maryland Foot Score (MFS), Olerud-Molander (OM) ankle score, American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, and occurrence of complications. Radiological outcomes were assessed by radiographs for multiple parameters, including calcaneal height, length, width, and Böhler's angle.
resultsThe patients were followed up for an average of 63.37 months. There was no significant difference in the final VAS score, MFS, OM score, AOFAS score, and the total incidence of complications between the two groups (P>0.05). Regarding the radiological outcome, there was also no significant difference in the reduction loss of calcaneal height, length, width, and Böhler's angle (P>0.05) after a one-year follow-up period. However, the rate of implant removal in the MIP group was significantly greater than that in the SW group (P< 0.05).
conclusionsMinimally invasive locking plate fixation versus screw fixation of DIACFs via sinus tarsi approach may yield comparable radiological and functional outcomes. The screw fixation group suggested a shorter surgical time and lower implant removal rate. Both surgical methods are viable options for DIACFs. However, further large-scale prospective studies are warranted to confirm these results.
