Systematic Review kya hai aur researchers ise evidence ko evaluate karne ke liye kaise use karte hain?

Ek vaivshtit samiksha ek sanrachit anusandhan vidhi hai jo kisi vishesh prashna se sambandhit sabhi uchh-guna adhyayano ko sangrahit, mulyankan aur sankshipt karne ke liye upayog ki jati hai. Yah darshata hai ki vartaman praman kya dikhata hai, har relevant adhyayan ka pareekshan karne ke dwara ek spasht, santulit drishtikon pradan karta hai, ek akela srot par nirbhar rahne ki bajaye.

Vaivshtit samiksha ek kathin, kadam-dar-kadam prakriya ka paalan karti hain jo pakshpat kam karta hai aur khoj ko barikh karna aasan banata hai. Isi bhaje se ise dawa, shiksha, niti nirman, aur kisi bhi kshetra mein jahaan nirnayon ko visvasniya anusandhan par nirbhar kiya jata hai, prabhavit roop se upyog kiya jata hai.

Anusandhanakaari jaise ki ek vaivshtit samiksha ke prashna ko spashtata aur vyapakta laane ke liye upayog karte hain. Ek baar mein kai adhyayano ka tulanakarne ke dwara, ve pravrittiyon ki anubhuti, gap pahachante hain, aur ve samarthit praman jise lagataar samarthit kiya jata hai, ko samajhte hain.

Ye hai ek saada vistaar vaivshtit samiksha ke mool vicharon ka:

• Kendrait anusandhan prashna – har samiksha ek gahre paribhahit prashna ke saath prarambh hoti hai taaki anusandhanakaari jaane ki kin adhyayano ko include karna hai aur kin ko exclude.
  
  

• Vyapak khoj neeti – samsthaan, reference suchi, aur kabhi-kabhi aprakashit sroton ko talash kiya jata hai taaki sabhi relevant adhyayan paaye ja sakein.
  
  

• Samosh aur chhodne ki ayam – anusandhanakaari ne kuche spaast niyam tayar kiye hai jo tayar adhyayano ko maante hai. Har adhyayan par ekahi niyam lagane se samiksha vastu-neerpeksh bani rahti hai.
  
  

• Adhyayan ganisht parikshan – ek baar adhyayan chune jate hain, har ek ka gaur se mulyankan kiya jata hai. Anusandhanakaari namuna aakar, design, pakshpat risk, aur phir kitna bhesvasniya ghatak lagta hai, par nazar dalte hain.
  
  

• Data pratyaharan aur visleshan – jankari ek sanrachit roop me ikhatta ki jaati hai. Anusandhanakaari phir prashnapari, aakritiyan pehchante hain aur samagra hai saboot ka sankalan kare.
  
  

• Saaf reporting – Vaivshtit samiksha har kadam ko saaf dikhata hai taaki doosree waha prakriya dhoraaye aur khoj ko ammol kar sake.

Vaivshtit samiksha maayne rakhti hain kyunki ye anumaanakaari ko alag-ekant results ki bhaa nahi lene se bachta hai. Balki, ye vidhi kai adhyayano ko ek wahi pradarshit karti hai ki kin khoj par lagataar ghatiyaan padha hai aur kin par nahi. Ye prastaav, maargdarsak, ya bhavishyak anusandhan ke liye ek aur visvasniya aadhar banaata hai.
