Does mini-midvastus approach have an advantageous effect on rapid recovery protocols over medial parapatellar approach in total knee arthroplasty?
Trial report in Joint diseases and related surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04796519 (A Comparison of Balance and Fall Risk in Patients With Unilateral and Bilateral Total Knee Arthroplasty), 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
objectivesThis study aims to compare the effects of mini-midvastus (MMV) versus medial parapatellar (MPP) approach on rapid recovery protocols during total knee arthroplasty (TKA). PATIENTS AND
methodsThis prospective, randomized, single-blinded study was performed in 54 patients (4 males, 50 females; mean age 64.1±6.4 years) diagnosed as primary knee osteoarthritis and planned for unilateral TKA between May 2018 and March 2019. Patients were randomly assigned as MMV (1 male, 26 females; mean age 65±6.4 years) and MPP (3 males, 24 females; mean age 63.2±6.3 years) groups. Rapid recovery TKA protocol and discharge criteria were assembled and all patients were evaluated preoperatively, and at postoperative first and third months. Length of hospital stay (LOS) was recorded for all patients. Hemoglobin and hematocrit values, radiologic assessment of alignment, knee range of motion (ROM), quadriceps muscle strength, visual analog scale (VAS), 30-sec chair-stand test, stair-climb test, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Short Form-36 (SF-36) were used for evaluations by blinded observers.
resultsThere was no significant difference in demographic variables between two groups. Operative time in MMV Group (78.1±2.7 min) was significantly longer than the MPP Group (65.9±2.6 min) (p<0.0005). LOSs in the MMV and MPP Groups were 27.6±3.1 hours and 29.1±6.7 hours with no significant difference. There was no statistically significant difference in postoperative measurements between groups in hemoglobin and hematocrit values, radiologic alignment of components, knee ROM, VAS, 30-sec chair-stand test, stair-climb test, WOMAC, KOOS, and SF-36 evaluations (p>0.05). In terms of quadriceps muscle strength gain, we could not find any difference between groups in pre- and postoperative difference of changes (p>0.05).
conclusionWith the use of contemporary rapid recovery protocols during TKA, MMV approach had no superiority over MPP approach when quadriceps muscle strength, LOS, pain, function, and quality of life were assessed. Longer operative time in the MMV approach compared to MPP approach may be considered as a disadvantage.
